If you think that the Pats are the only ones who try to gain a competetive advantage ( aka "cheating) by stealing signs or any number of other tactics that are common place in the league, then you are a fucking moron.
People will always go after whoever is on top. Sure, they deserve the consequences. People boo-hooing about it are a bunch of sorry saps though doing nothing more than blowing it out of proportion.
Belichick is far from a moron. A guy on the sideline with a video camera is hardly a very intelligent tactic.
