The most important player on D after Revis is.....

[IndianPat]

McCourty,Browner, Chung (Harmon) along with Revis are reason why this defense gave up only 3 points in total in the fourth quarters of the playoffs. Patriots have never had a back court like this in the 30 years I have been watching them. So, I would go with McCourty as the most imp. after Revis.
(Despite my pride in their achievement, I admit I was quite disheartened in the manner in which Ravens and Seahawks moved the ball on us earlier in the game and on the final drive in both games).
