I'm not that confident in the Giants but I think they will cover this number. Dexter is big on it which I am comfortable with. Teasing the Giants up to 10.5 is smart in my opinion- you're getting that hook and 10 points in this type of game is a lot.
I can see this being a back and forth type game with at least 20 points scored by each team. Demarco Murray will be in beast mode tonight for Dallas.
For the Giants, I see a few big plays in the offense and special teams being the reason they stay in this game. Dallas blitzes a lot so either Manning is going down or Dallas is gonna get exposed on a few plays down field.
