I think that the Pats are among the most undervalued teams in the NFL right now. I've watched their last 3 games and seen steady improvement in their offensive rhythm as Brady gets more accustomed to his new WRs. Also, Blount has really stepped up as a reliable #1 power RB, taking pressure off the passing game.
I can totally understand the mindset that they've been lucky thusfar to win with so many problems, but I think they're only going to keep getting better as the season progresses. And coming off that horrible game last week and playing at home, it was a pretty good situational spot for them.
