Every HC covers their mouth with play cards when calling plays or talking over the headset. People have been trying to read lips or steal calls for ages. So, Mangini gets pissy and calls out his former team on it and suddenly a bunch of naive fans/haters accuse the Pats of cheating? I'm a Niners fan (not Pats fan) and I think this is ridiculous. The Pats are simply a smart and well coached team. If you really are naive enough to think this hasn't been going on forever, how would you feel if your team (and only your team) was banned from hiding conversations on the sideline?
