Trying to look at this through the eyes of a Patriots Hater...
Pete Carroll showed that he wasn't above breaking NCAA rules while he was at USC. Why should we believe he's decided to follow the letter of the law while in Seattle? They've been fined 2 or 3 times for breaking the offseason practice rules. Also, while it occurred after he left, USC was caught using deflated footballs during a game. They could have gotten that idea from Carroll.
It's pretty clear: There's a pattern of behavior, the Seahawks are repeat offenders and there's photographic proof. Give me the cellphones from the punter and the equipment guys and I guarantee you there's an incriminating word or phrase in their texts or emails from the past year. The only question now is, how many first round picks will be taken away, how long will the suspension(s) be, and how many millions are the Seahawks getting fined.
