While Peyton is a very sharp QB, his o-line is his secret weapon. On a side note, Gonzales the possesion WR was a brilliant aquisition, a Wes Welker type.
It's not a Manning vs. Brady issue. Bill and Tony are the guys that decide to take their foot off the gas.
And last night was one of the first times Brady has done that. It was a smart move. That NE defense is pretty worn out at this point. They need some rest or it could hurt them in the postseason.
