LOL what? The defense was bad all season. You can't expect the D to be top notch EVERY year. It was ranked 31st in 2011 and only managed to give up 21 points in the SB. On the other hand, the offense was ranked 2nd and scored at 32 PPG. In the super bowl the offense scored only 17. The truth is the Pats didn't deserve to be in the SB. The defense bailed out Tommy in the AFCCG vs Baltimore (239 yards, 2 INTs, 0 TDs, 57.5 passer rating).
Being good all season at something and then suddenly not showing up is called...choking.
As far as the intentional ground is called, Brady had the ball as Tuck was coming after him. Brady didn't even argue with the refs on that one. He knew.
