Every player who attends the Scouting Combine must submit to drug testing. With two of the players who were tested at the Scouting Combine in 2017 generating positive tests via diluted samples, there’s an important point to keep in mind when deciding whether the explanation for the failed drug test passes the smell test.
The samples are collected very early in the morning, with the players often getting the “wakey wakey” business before doing their business into a cup. So the diluted samples either resulted from a player drinking huge amounts of water before going to be and then: (1) failing asleep with a rapidly-filling bladder; and (2) sleeping through the night with a very full bladder, or from a guy waking up early and drinking copious amounts of water in order to ensure that certain substances won’t be detected in the sample.
The statement issued on behalf of former Michigan defensive back Jabrill Peppers accounts for this dynamic by pointing out that the player “was being pumped with fluids, drinking 8-10 bottles of water before he went to bed, because he was the first guy to work out two days for the LBs and DBs.”
Is it possible he actually drank that much water before going to sleep, fell asleep with that much water in his system, and slept through the night without having to get up to unload most of the 8-10 bottles of water before proving a sample that wasn’t dilute? Sure. But it’s also possible that Foster, Peppers, and anyone else who generated a test sufficiently dilute to be regarded as an effort to beat the test deliberately ingested extra water to ensure that any banned substances would be undetectable in a sample of urine that had been overloaded with water.
Either way, teams that pick either guy will have to assume the risk that the players failed their first major football-or-banned-substance test, and that they’ll fail enough of the various future football-or-banned-substance tests to come to result in their inability to play football.
Should it be this way, with teams testing player urine to determine what they’re doing on their own personal time? Nope. But until the rule changes, the players need to be able to pass the test.
