I will gladly take the ugly win. I think it is good to win a game in which you play bad on both times of the ball (the offense was not great today - two of the TD drives were 13 and 39 yards).
However, looking at the season as a whole, the Patriots have played three games where the dominated the other team (Titans, Bills game 1, and Rams). One game that ended closer than it really was (Broncos) and 5 games that one play either way could have changed the outcome (Cardinals, Ravens, Seahawks, Jets and Bills game 2). The could easily be 9-0 or 4-5.
The good news is that they won the last two "close" games they played after dropping the first three. Do they need to play better (and more importantly more consistently) if they are going back to the Super Bowl? Yes. However, they still have a shot at a bye (even the No. 1 seed if Houston falls to the Bears tonight).
Not sure why I am optimistic after that game. Basically, once the Bills got the ball I was convinced they would score. I was honestly, hoping they would score quick and give the Pats a time for a shot at game-winning FG, but that wasn't necessary.
It was ugly, but I will take it...
