Pats win in a low scoring affair. I think both teams play their starters in the first half and then the Giants will see where the game stands and evaluate how they play.
If the Pats are leading by a significant amount I look for the Giants to start feeding subs into the game.
If the game is close or the Giants are winning, I look for the Giants to get caught up in stoppinng the Pats and play for the win.
If the Pats are winning at the half I look for a run fest in the second half. Grind the clock, speed up the game everyone goes home unscathed.
So I predict a quick game, Pats win 20-13.
