You do realize pre Brady he was a failure as a Browns head coach, right? He went 36-44 in 5 seasons there with 1 playoff season and post Brady he hasn't had any success either. And Parcells was the HC of those 2 Giants Super Bowls. The Bills would have won if they weren't so stubborn about their game plan. Belichick himself said that they invited the Bills to run the whole game and the Bills chose not to. When they did, Thurman went for 135 yards on 15 carries. Imagine if he gets 25 or 30 carries. We get a Lombardi. The Bills stubbornness is not something to give Belichick credit for
