The Patriots will win because...

1) Tom Brady will get the time from his offensive line to exploit the Cover-2 of the Bears (or Tampa 2 or Chicago 2 or whatever).

2) New England really needs this game to prove to itself that it still has the will to decalre its home field sacred (if plastic) turf by winning a game against a decent team at Gillette Stadium.

3) The Bears aren't going to be in a position to deal with a defense as potent as New England's and Rex Grossman will be reduced to a quivering pile of jell-o with a face mask and a hand towel.
