NFL should release all PSI measurements

Last week, Commissioner Roger Goodell said he doesn’t know whether the PSI measurements taken randomly throughout the season will be released to the public.

They should be.

[I]t’s a big mistake if kept under wraps,” writes Peter King of TheMMQB.com. “It has to be made public, or else the public’s going to think the NFL is hiding the results. The NFL can’t simply say, ‘The balls were in compliance.’ Goodell said before the Wells report was released that the league would be totally transparent and we would know what Wells knew when Wells finished the report. So why is this different? I can guess. The NFL wants to reserve the right to not issue the measurements if it makes the league’s case against Tom Brady look bad.”

Peter is right. It’s a point that was made during a recent visit from Tom Curran of CSN New England to PFT Live. If the numbers support the notion that the Patriots deflated the footballs, the numbers are more likely to be released. If the numbers don’t, the numbers are less likely to be released.

Goodell said that the purpose of the random checks will be to ensure compliance with the rules. The reality is that the NFL still has woefully incomplete data regarding the effects of temperature and weather conditions on PSI. Every ball used in every game should be measured, both at halftime and after the game ends, which would provide extensive data for determining whether the footballs used by the Patriots lost air pressure due to foul play or the natural operation of the Ideal Gas Law.

Why wouldn’t the league want that? Because the league doesn’t want to be made to look worse that it already does for how it mishandled #DeflateGate. If the limited PSI numbers make the league look bad, the league will do everything it can to keep the media and the fans from getting a look at them.

  1. Of course they should but this was all a sham in the first place.

    Unfortunately for the science deniers in the league they are wrong. Period. They fabricated this and are desperate for any straw they can grasp at that might allow them the tiniest shred of credibility, which of course is impossible for them to ever restore.

    Goodell is a vile, lying, disgusting excuse of a commissioner and he must go.

  2. With the NFL appealing their court loss in the Brady suspension, they will only release the info if it helps their case. That they haven’t released it, suggests it hurts their case.

  3. There is no reason to even think about PSI until it gets cold and rainy. That’s when QBs start messing around with the balls. Good weather footballs are easy for anyone to grip.

  4. “It has to be made public, or else the public’s going to think the NFL is hiding the results.”

    Uh, no. “The Public” is not going to think that. Only a few east coast “sports journalists” think that.

    The Public thinks Tom Brady is a cheater and it’s been proven six-ways from Sunday.

  5. maybe it’s the cynic in me but I can’t help but think the ‘random checks’ will be randomly confined to games played indoors with a few done in the challenging temperature extremes in some place like…San Diego

  6. Goodall owes it to everyone involved to release the numbers, including the Pats homers and especially the Pats haters. You dragged everyone along for just about a year and you don’t want to be “transparent”??? You freaking coward!!!

  7. Why would they do that? It’ll just make them look worse than they already do. They won’t release them because it will probably show that nothing happened during “Delategate”

  8. PSI should be put to bed for NFL history. It is an ugly chapter, much like the witch hunts of Puritan Massachusetts and 1950s Washington, D.C. Goodell, if he was not the obedient servant of a billionaire class, would be out on his derriere.

    As for Peter King, he lost any credibility on this subject months ago. Tom Brady makes Goodell, Grigson, Wells, Irsay, Harbaugh, Pash, Vincent, Kravitz, Jones, Johnson, Mortensen, ESPN, and others to numerous to note every game day.

  9. “Well” Goodell released false information regarding the psi of the balls to Morty in the first darn place.

    If this psi issue is so important to the game, so much so that the GOAT must have his 15 year career destroyed over it, why aren’t all the balls checked in every game at the beginning, half and the end and the results made public?

    Why is the league trying to destroy Tom Brady while still handling ball psi willy nilly?

  10. The Patriots should start releasing their PSI measurements of all the balls given to the Refs before the game. It kind of forces the league’s hand to be transparent in compliance with the league rules for equipment.

  11. I grew up in Buffalo. Sports equipment was kept in the unheated garage. Basketballs and Footballs would lose PSI in the Winter months and need to be pumped up.
    However, this occured over days or weeks, not hours. If you want to test, pump up a football and throw it in the refrigerator for 2 hours, ( 38 degrees ) simulating halftime. DYI and report the results. Im sure that everywhere but New England the ball will retain it’s pressure for 2 hours.

  12. Of course they should, but once/if they did, the Pats would be entitled to get their picks back – actually they already are entitled to them, but this makes the league even worse if that is possible.

  13. The psi data will never be released because it will prove that the “NFL made a mountain out of a molehill,” to quote one anonymous afc owner. Every Brady td pass illustrates just how badly the NFL mishandled this purported scandal.

    The NFL should just let this one go and stop pretending like they actually care about psi data at all. They already robbed the patriots of a first round pick, so mission accomplished on park ave.

  14. How exactly has that been proven “6 ways to sunday”?

    Maybe you should have let Roger in on all the facts you’ve discovered he could have used you when he was getting torched in court

  15. Mike, has Goodell released the names of the individuals that leaked to Kravitz and Mortensen? Of course he hasn’t. Why isn’t he asked this question in every time he is seen in public?

    Who in their right mind would believe any psi stats published or unpublished by the NFL? The whole history of deflategate was a series of NFL lies and media manipulation . King is an NFL suck up who pretends to be an arbitrator of fairness. The real independent investigators have already come down on the side of Tom Brady. This isn’t any less resolved science than climate change. The deniers, like Goodell, have a reason they deny and no objective fact will keep them from that dogma.

  16. the Patriots will do what is in the best interest of them and them alone……they have proven time and time over they cant be trusted….

    There I made it more believe able to those outside of New England.

  17. Releasing this kind of info will surely damage the shield and damage the integrity of the league.

    I grew up in Northern Vermont and I can assure you that you have no idea what you are talking about if you honestly believe leaving a basketball\football overnight (let alone hours) won’t lose air pressure. Heck even Exponent would argue with you on what you just claimed.

  19. .
    The hare brained appeal and the surreptitious collection of random anonymous psi findings are just a desperate attempt to find justification for fining the Patriots one million dollars and seizing two draft choices.

    It will be a travesty if the Patriots sanctions are not lifted since there’s been no actual proof that a transgression even occurred.
    .

  20. Haters do not want this data released. The data will prove the Pats aren’t cheaters and that their teams are consistently inferior which will cause their heads to explode and crush their morale.

  21. “Why bother?
    There hasn’t been a game played in temps under 30 degrees yet.”

    This illustrates that far too many people still just don’t get it.

    It’s the CHANGE IN TEMPERATURE that matters. This means that if you take the ball from a cooler area to a warmer area, the pressure will INCREASE.

    Releasing ALL the data allows for a larger dataset for the scientific analysis, with regards to both increasing and decreasing pressures. Even just this preliminary data could determine the likelihood of atmospheric conditions causing the deflation/inflation naturally.

  22. If the NFL wanted scientifically valid data, they’d be doing something more than spotty random testing. The extent of their effort indicates the extent of their interest in the question.

  23. Roger, Come on man.
    The shield is so tarnished now you couldn’t clean it with a 55 gallon drum of ketchup.
    At the end of the regular season let’s see the numbers from North outside stadiums, North dome stadiums and South stadiums. The proof will be in th pudding.
    Or don’t you have enough air in you’re own balls?

  24. I can’t believe some in the media are still going on about this crap. Let. It. Go.

    I don’t think the Pats equipment guys and Brady did anything and it was just the league screwing up royally on handling a scientific fact (that air pressure drops as the temperature drops) but I don’t understand the point of this article and how it ties into making Brady or themselves look bad or why the media has to still go on about this. Move on.

  25. Why don’t they just put the PSI of the ball in play on the scoreboard so everybody knows…everybody knows.
    -L Cohen

  26. No one with an ounce of intelligence or insight believes anything Goodell or the NFL has to say anyways. They have lost all credibility. I would be worried that anything they released would be falsified like the original PSI numbers or Brady’s appeal testimony.

    How can anyone ever trust anything coming from Goodell and his minions?

  27. If you want to know what happens to PSI in a football as it cools, just pump up a football to 13 psi, put it in a fridge for a few hours, then measure the pressure! Every 20 degrees or so of T drop, you lose about 1 psi of Pressure.

    Which is what happened in the AFCCG.

    The NFL does not need to “test” the temperature/pressure relationship of gasses, because since 1702 it’s been a pretty much settled concept.

    Since they are doing it, though, transparency is nice. But overall the idea is silly.

    Nobody took a measurable amount of air out of any Patriots football in the AFCCG. By now even the NFL knows that.

  28. Instead of saying the “Ideal Gas Law” makes the air pressure change, please say “…physics…”

    The Ideal Gas Law describes/predicts the behavior. A small thing, but it makes my scientific training itch when written that way.

    —————————-

    Not true at all, actually. From the beginning of the pre-season to now, there have been widely varying temperatures at the time of kickoff. What’s important, is the temperature at kickoff in relation to the room the balls were inflated in. If, for the sake of this discussion we were to accept that the normal coaches lockerroom is 72 degrees, any game played at a higher temperature than that, would register an INCREASE in PSI, after being outside for a period of time.

    And game played in inclement weather, would also have a variation in PSI, due to the interaction of water with leather. All of these variables are extremely important to this question. Unfortunately, I think the NFL is basically admitting guilt here. As most logical individuals have pointed out, if it helped their case, they’d most certainly be broadcasting the results. One can only conclude that is simply not the case.

    Keep in mind, even if it’s 5 degrees warmer or colder, the rate at which the PSI does or does not change, lends weight to either the suspicion of tampering, or that the league jumped the gun w/o understanding a very basic scientific law.

  30. “I think the most important thing we’re trying to ascertain is that the balls in play are within the regulations that were established,” Goodell said. “That’s the core of the issue: Protecting the integrity of the game and making sure the game is played within the rules. We’re a game of rules, the rules need to be followed by everyone and the objective there is to make sure the rules are being followed.” – Roger Goodell

    This moron is going to try and legislate mother nature out of the game. What are you going to do, add air as the game goes on?

    Change the sacred rule to “starting pressure of 12.5 – 13.5” and let the game be played as it has been played for 70+ years now.

    And maybe even try inflating the balls pre-game on the sidelines in the same environment where the game will be played.

  31. Brady was caught cheating, and the Pats were fined, had draft picks taken away, and Brady was suspended. One judge said that although Brady was guilty of cheating, he shouldn’t be suspended for it, since he wasn’t warned. The rest of the penalties have been enforced. I doubt that anyone else will mess around with the balls, but the league should monitor the Patriots footballs. Kinda like parole.

  32. Does Goodell not understand that every middle school science class in the northeast (if not the entire country) is going to be teaching the ideal gas law by taking footballs from the classroom to the outdoors and measuring them before and after the class? If the NFL won’t release the data, youtube will be filled with the experiments and results—making the NFL look really small if they don’t release the results also…..but then we must all remember Goodell’s law:
    If there are two ways to do something, one good and one bad; the NFL will do it the bad way–every time.

    I would imagine what you’re describing is condensation which is what happens when a cool object comes in contact with warmer air, a jug of water from an air-conditioned store going out into 90+ degree weather would do it….but you’re exactly right that air and temperature react to each other and when you add in atmospheric pressure….bingo!

  37. idoubtiwillbother says:

    ———————————————————-
    The Ideal Gas Law is a hypothetical approximation which has never been demonstrated in a 52 degree football stadium after the balls were taken into a locked room and deflated.

  38. The league could easily solve many problems with chips in the balls for both goal line technology and psi monitoring. At this point its almost childishly easy to add that technology.

    The league however will never do so because that would prevent them from manipulating games. How can they disallow a TD if the view isn’t clear that the crossed the goal line if there’s a chip that says yes it did ?

    Doing so would take human decision making out of quite a lot of the decisions that the league wants control of, plain and simple.

  39. Goodell is a monstrous liar. He doesn’t know if they will be released or not because he doesn’t know the results yet. They will be released if they support the NFL; they will be hidden forever if they support Brady.

    In other news, the whole procedure for collecting the measurements is a giant head fake. There is no attempt in the procedures as described that would replicate what happened last January. This is the NFL at its absolute worst.

  40. Not only should they release the information. They should record the PSI for every single game.

  41. Wow. You’re still obsessed with Brady’s balls. Let them go. At least til next offseason. You’re the only one talking about this. Jeez.

  42. Goodell will treat this like a promise he made to take his cousin to the Prom.

    Going through the motions but he knows there’s no happy ending.

  43. Information gets leaked when it suits the NFL and Goodell (not Tom Brady). The psi in footballs will really start to decline when the weather gets cold.

  44. Let’s face it. This information will get leaked no matter what. It was leaked that the NFL got the Ray Rice tape in APril (they of course denied it and the league-financed report never mentioned it but of course they did) so the proper measurements here will be leaked as well, and if they support Brady in any way, I do not see how owners could keep Goodell after that.

  45. The NFL reminds me of the Vatican. They both preach, call innocent people sinners, while they cover up their own sins. I don’t think I need to explain.

    ========================================

    Pats fan here – let’s not make stuff up like the haters do. Berman did ask (pointedly) about the absence of *direct* evidence against Brady, but consistently maintained the distinction between direct and circumstantial evidence throughout that entire line of questioning, and never made any declarations of his own that even remotely resemble the quote attributed to him above. If you want to quote Berman, then I suggest you quote directly from the actual (readily available) source material rather than repeat invented quotes simply because they support your point of view.

  47. This is hilarious. The NFL Headquarters is packed with ex-New York Jets execs and the whole carny act has really showed it to be a joke. Forget about data from the NFL. The Ideal Gas Law will show the NFL’s entire effort was a bunk witch hunt and they don’t want to look even worse than they already do.

    The great part is, I have 12 Wilson Official NFL footballs and myself and others will be doing actual independent testing, not the bs the NFL calls independent. The facts will be known and just from last year’s actual tests, it’s already obvious. I have a box truck available I take to games and will fill the footballs to 12.5 PSI at 72 degrees within the truck, put them all in a bag, bring them out, get them wet over the right period of time, at the right outside temperature-it was around 50 degrees, but I will get that perfect along with testing at other temperatures just to show how much the Ideal Gas Law effects PSI at lower temperatures. The timing will all be correct and the laughable fact that the NFL stopped measuring the Colts footballs after doing four of them-3 of 4 were under 12.5 PSI lololol-because they “Ran out of time” just adds to the comedy.

    I even have the two gauges used. The NFL would have hid that if they could but sorry guys. The Ideal Gas Law refers to the formula that determines the changes in gases based on various factors, including but not limited to volume, pressure, and temperature. I’m going to get these as close to perfect as possible, a hell of a lot closer to perfect than the NFL ever will.

    I’ve already been in touch with people across the northern part of the U.S. and the PSI readings in cold weather cities across the U.S. will want to be buried by the NFL without question. This whole carny act should never have happened but it will be fun to watch the NFL Headquarters (The NY Jets Retirement home) look ridiculous yet again.

  48. It doesn’t matter what information they release if there is not an independent party to monitor the testing of the footballs. The NFL could just lie about what the measurements were.

  49. Everyone knows the Patriots would be 2-14 every year without spygate.

    Everyone knows Brady is only a good QB with deflated footballs.

    Belichick was a bad coach in Cleveland and spygate made him great.

    Brady is a system QB.

  51. If the NFL was serious about understanding how psi changes during games they could easily hire an outside company (hopefully a company unlike Exponent) to oversee a comprehensive independent study. It would be pricey but far less expensive than Ted Well$ and the expenses incurred for previous buffoonery.

    Get real data, disseminate the data, clear the air, move along.

    As long as the NFL is the entity studying the NFL in this instance any information provided can only be dubious.

  52. Goodell’s misguided appeal has no shot of winning. Berman made a well-reasoned and thoughtful decision in accordance with the law.

    The fact that Goodell is setting himself up for even more embarrassment with a ridiculous appeal that has zero to do with “integirty” than he has already suffered is astounding.

    Just how stupid is that man?

  56. If the NFL doesn’t release this data then we’ll all know what we thought we knew…The NFL ran a sting that went completely awry.

    The NFL MUST release this data. This way we’ll all know if the Patriots/Tom Brady cheated and that the suspension should be served and the draft picks taken.

    If the Patriots/Brady are found innocent, it’s easy…Return the draft picks…I really don’t think that the Patriots/Kraft care about the money.

    Releasing all the data would make it easier for the public to understand how the air pressure changes as a function of temperature.

    There’s no good reason for the NFL to not release the data. If they do so we’re going to have to assume that the data shows that the NFL made a mistake in prosecuting the Brady case as vigorously as they did.

    Of course, anybody with familiarity with science already knows that.

    Actual quote

    “Is there a text in which Mr. Brady instructs someone to put a needle in a football? No, there is not such direct evidence,” league lawyer Daniel Nash said under questioning from U.S. District Judge Richard Berman Wednesday in Manhattan federal court.

    At no point did Berman give credence to the notion that circumstantial evidence should be considered a reasonable substitute for direct evidence, as you imply.

    Berman also said “What is the evidence of a scheme or conspiracy that covers the Jan. 15 game? I’m having trouble finding it.”

    Clearly Judge Berman has doubts about the soundness of the NFL’s fact-finding, even though that was not legally challengeable in his appeals court.

  59. After seeing the nfl leak lies to espn’s Mortensen after the AFCCG and refuse many requests by the Pats to correct the lies, seeing the nfl’s Dave Gardi send an official nfl letter to the Pats with the blatant lie of one ball measuring 10.1 psi and repeating the lie about the Colts measurements, seeing the incredible deceit in the Wells report including the falsification of transient curve data, and seeing Goodell being exposed as a liar when the appeal transcripts were unexpectedly made public by the judge it is clear that the nfl will just fudge the measurements to make themselves look better.

    __________________________________

    There’s one more factor (in addition to temperature and wetness) that needs to be part of your testing … wind.

    At game time of the AFCCG the wind speed at Foxboro was in the upper teens with gusts approaching 30 mph. Expose a wet object to wind and there will be evaporative cooling (when the wet object in question is skin, the weather folks call this wind chill). Expose a wet football to wind and the temperature of the ball can be significantly lower than the temperature of the ambient air (something that Exponent never considered). It’s the temperature of the football that matters, not the temperature of the air around it.
