“Of course it’s a big deal,” said a defensive coordinator. “You go try to throw a ball in wet conditions that is fully inflated, and then throw one that has less air. Of course you’re going to get a better grip. It’s a definite advantage. And look which team it is. Not a surprise.”
An AFC defensive coach told me: “It pisses us off. We’re talking about the integrity of the game, respect for the game. That should mean something to you. You don’t have to look for every gray area to exploit. It’s like the ineligible player thing. [The Ravens complained that the Patriots were working too fast when players were reporting as ineligible and not allowing the defense time to change personnel, as is required.] That violates the spirit of the rule.
“[Belichick] is a great coach, and they are a great team. It’s just a shame that they feel the need to do these things. If you don’t respect the game, I lose respect for you.”
