I think 8-8 or 9-7 is more realistic. I think Buffalo and the Jets are both better than the Patriots right now (and they both have very weak schedules too). And even then, it's an ugly 9-7.
This is where I remind you that the Patriots new starting QB hasn't started a meaningful game in 9 years. Moss is less effective when you can't get the ball to him downfield, Welker will be a great deal less effective when you can't spread the field, and the running game, which at times looked like an Achilles heel last year, will be less effective when the defense can actually play to defend the run without worrying about getting burned by Moss and Stallworth.
And that's not to mention the defense won't have the comfort of playing with 20+ point leads and teams will actually be able to keep them honest. It's an awful lot easier to play defense when you know the other team has to throw the football. The defense actually looked somewhat mediocre (particularly their run defense) and, towards the end of games, worn down in games where the other team didn't have to abandon their running game in the first half -- and that was with Asante Samuel.
You're talking about replacing one of the greatest of all-time with one of the worst in the League right now.
