You guys are making this way more serious than it really is. Teams have been stealing signals from other teams for decades. The scouts job is to steal signals. Why do you think they cover their mouths when they talk to the QB, so the opposition can't read their lips.
There are a lot of plays, that this old grandmother who never played football knows what the defense is going to do.
Is it wrong - yes
Are the Pats the only team doing it - no
Is the penalty harsh enough - probably not
But penalizing a team 700 mill is a bit of overkill. Having the fans lose their team by moving it to another city - well we sure didn't like it. Banning the coaches doesn't serve any purpose either - how many coaches are you going to ban, Crennel, Mangini also - as they were part of the Pats.
If Mangini was that much against it, why did he not speak up sooner while he was on the Pats staff or last year when he had left. No - he waited til they were playing him.
In the end, even if you know what the defense is going to do, the players still have to make the throw, make the catch, miss the tackles, the oline still needs to block. Then you defense needs to stop the other team. Winning or losing a game is still up to the players on the field, not the coaches.
