Does anyone think Bill is stupid? that answer is NO!
Let's ask Bill if he's caught other teams doing the same thing. I would bet, the reason Goodell destroyed the tapes so quickly is that there was evidence of other teams (it's called CYA )doing similar things.
Goodell wanted this to go away quickly and quietly if he had to open investigations of other teams this would REALLY get ugly!!!!
Focus on the Pat's all you want this isn't over yet.
