I'm a big skeptic and tend to dismiss almost all "conspiracy theories." But there is a LOT of circumstantial evidence supporting the claim that the Pats taped the Rams' practices before SB 36. (Not to mention Deflategate and the fines and the taping of opponents signals).
Belichick is a cheater of the highest order. He's also a gifted coach. If he has to wait a couple years to get in, fine. Let him have an asterisk next to his name.
