Technically, that’s true. Romo’s seven-year deal carries $55 million guaranteed; Flacco’s six-year contract has $52 million.
Apart from the obvious fact that Flacco gets more guaranteed money per year is the reality that Romo already was destined to make $11.5 million in 2013. So the “new” guarantee for Romo is only (only?) $44 million for the six extra years of commitment.
It’s still impossible to know the practical duration and value of Romo’s contract without seeing the full deal. For Flacco, he’ll get $62 million over three years and then the Ravens likely will have to figure out a solution for a cap number that will be approaching $29 million in 2016. For Romo, we’ll find out once the official numbers are in.
