Ok, Well I guess we have to agree to disagree Chris, I wouldnt say the penalties by the offensive lineman were as big a deal as an 11 point swing from the patriots offense.
Couple of things about the mistakes you mentioned Rondo:
1.) Go back and watch that Schoebel interception. That was not nearly as much of a mistake as it was Schoebel reading the play properly, staying home in the passing lane and then jumping 28" from a standing position to one hand catch a ball thrown over his head. Phenomenally athletic and intelligent play by Schoebel, A DEFENSIVE LINEMAN, that should be given credit to him to not made into some mistake of Brady's.
2.)Thomas penalty, while a huge mistake, was no guarantee of the Bills not picking up the first down on the very next play or couple of plays. You are assuming that that sack would have been a drive killer but on several occasions not only during that drive but others, the Bills had been picking up big, big first downs on third down. Say what you want but I don't see that play as costing the Pats a TD given the way Buffalo was performing on that drive and considering they still had 2nd and 2rd down to go. They made a 3rd and 15, a 3rd and 3 and a 3rd and 8 on that drive alone.
Also, let's face it, the biggest mistake of the game occurred on the Bills side of the ball not the Pats. McKelvin takes a knee and the Bills can pick up just one first down and the game is over Bills win. The mistake that decided the game was a Bills mistake and the Pats played some uninspired ball. But the Pats did in no way shape or form deserve to win this game big. They didn't play that well.
