He has the Kevin Faulk role with the Pats. Since the Pats change their game plan week to week, depending on opponent situations, some games , he is heavily involved, and some games, he barely plays. It all depends on match ups, and the defenses he is running against, and how best to use him.
But he is very valuable, as small as he is, he is the Pats best blocking RB, he reads blitzes well, and Brady trusts him with pass protection, to assign him the free running LB, or safety. Because he blocks so well, he is great on 3rd and long situations, he can either stay in black allowing extra time for Brady and for longer routes to develop, or he can get the ball in space and make things happen.
And he runs between the tackles surprisingly well, you would think his game would be bouncing to the outside, and playing with space, but he sneaks behind the big offensive lineman, finds the smallest crevice of a hole, and gets his yards that way.
I don't know weather it was a good or bad move for the jets to let him go, or keep him, I am not familiar with the jets roster enough at the time to make a informed opinion, but I am glad that he is on the Pats, and he is not a limited role player, he plays a major role.
The only thing on the jets I can think of, is I always think the jets lack 53 man roster depth, They really don't put a lot of thought in the bottom of the roster, so when players get injured, they have nothing behind them. And teh jets run a very limited rotation in lots of positions, where teams rotate personel a lot more. But the jets have always been surprisingly lucky when it comes to injuries, this year they lose Revis and Holmes, which were big losses, but little else. Most teams have a revolving door at Dline and oline, and secondary folks, and tons of starters go down. the jets seem to always stay healthy. But they also seem to have such little depth, I am shocked a football player like Woodhead regardless of depth at a position, could not find a roster spot on the Jets.
