I know these prediction posts are generally not worth much, and I am generally a pretty conservative poster, but here goes. I think Patrick has been steaming ever since the touchdown pass to Jimmy Graham last Sunday. He put the responsibility for that on himself and he was feeling pretty upset about it (to put in mildly) until Alex hit Vernon with the last TD.
As prepared and motivated as Willis always is, I think he will take it to another level against the Giants on Sunday. I would look for the following:
1) monster play against the run, freeing Goldson and Whitner to concentrate fully on pass coverage (ok, he does that every week),
2) man covering the Giants tight end, who is good but not especially fast, without help and shutting him down (allowing our safeties to help the corners with Nicks, Cruz and Manningham),
3) several big impact plays including a sack, forced fumbles and a fumble recovery.
The third item, of course, contains the monster plays that can transform a game. (Like the hit by Whitner last Sunday.)
In my imagination, Patrick's experience, how he felt when Graham scored on his coverage, will enable him to transcend to a even higher plane of competitive fire and intensity. (Sort of like when Gandalf comes back from near death as Gandalf the White in LOTR.) A great warrior transformed and reforged to become even greater.
