It was a different game, different situation, and different officiating crew. So it's hard to compare. But what's hard as a Pats fan to deal with is that these were just a couple of games apart, against the same opponent. The Allen play....he was in the air, still moving forward, reaching for the first down marker, when the Pats' defender (forget who) BARELY nudged him. Allen had not yet even established himself as being out of bounds, as he could have, even in that moment, lateraled the ball backward to a teammate and the play would have been still live. So the Pats' defender actually had the right to light him up at that moment. Not only didn't he do that, he barely touched him. 15 yard personal foul penalty.
Then Mac is clearly hit WELL out of bounds, and then dragged down. Maybe you can say the defender was trying to hold him up. It's too hard to judge intent there. Clearly he hit him, and the only reason he would have had to hold him up would be because he hit him in the first place. Not only is that penalty taken away after a flag had been thrown, the Pats, in frustration, are issued a 15 yard penalty themselves.
So it would have been for the New England offense, first down at the Buffalo 38 with 1:22 left (and a timeout remaining). Plenty of time to try for a touchdown or at least kick a field goal that would have given the Pats some momentum going into the half. Instead, that entire sequence pushed the Patriots back to their own 32.
So on a play where the Bills' defender committed a penalty, it was the Patriots who lost *30* yards of field position. I mean....what on earth?
Not to mention (yet here I go mentioning it) the ridiculous play in the fourth quarter when Mac is lit up after sliding, and David Andrews gets in the guy's face - not a single push or punch or shove delivered...just got in the guy's face to stand up for his QB who was given a total cheap shot - and the refs flag ANDREWS for an unsportsmanlike conduct penalty. The Pats scored anyway so maybe it doesn't matter, but come on.
