You're probably right. The Patriots know even if T.O. plays he won't be 100%. If he does play he's going to get hammered on every play.
But the thing is TO totally changes the Eagles passing game, he's the only contact receiver they have, the Pats will need slightly different game plans with TO vs without. Or maybe Belichick just won't worry about it since there's no way TO will be at 100% and probably won't be able to sustain the contact. To me this is the fun part of the Superbowl, watching the coaches monkey with each other. So how many times in the last 5 days has Belichick said the Eagles are a great team?
