They got busted for taking sideline video of the other teams' defensive coaches sending in hand signals - aka Spygate. Nobody's denying that. But that's it. And lost in the hysteria was that the rule against that was new in 2006, there was no such rule when they won their SB's in 2001-2004. So call it whatever you want, it was not relevant to any season where they actually won anything.
There ie emphatic proof they got busted in 2006 at the beginning of the season and a memo was sent out and they got busted again in 2007 after being warned in 2006. So they violated the rules a year after the fact. Thus, the idea that Bill Bellichek misinterpreted the rules is a LIE.
In fact, in 2007, the beginning of the year, Norv Turner in September of 2007, right when the news broke about Mangini, when visiting Gilette stadium locked up the playbooks in lockers. Everybody essentially acknowledged that what they were doing was pretty much unheard of, while acknowledging they weren't sure how much it could of helped. And that just shows how ignorant most people were to their cheating.
And the guys doing the stealing were dressed up as COACHES, so not only were they potentially taping from the sidelines, they could have possibly been taking audio as well. Mangini knew exactly the techniques being employed, because he pointed out the guy specifically who was dressed up in 2007. The Pats were doing it for years.
Further, the Matt Walsh tapes were about taping the walk-throughs of practices which is illegal. What makes you think that was legal during the SB years? So if they dress up as coaches in 2006 and still violate the rules in 2007 after the memo, what makes anyone think that they weren't dressing up and taping practices of walk-throughs? They just started happening to disguise themselves in 2006?
And implicitly the Butler INT implicates BB again through his own words when he said they knew it was essentially coming, because Seattle does it all the time, and they practiced for it specifically and told the defense to look out for it. If taping walk-throughs have no bearing on winning a game, than why is BB saying knowing the actual play is important? Only a homer would try and downplay Spygate.
