I think his lack of success recently has a lot more to do with his level of frustration of being in a losing environment more than a deterioration of his physical skills. When this kid is on, he is one of the leaugue's better RBs. He has great running skills, excellent vision and he's a big, strong back @ 6-1, 230 who is deceptlively fast. He runs hard and low and knows how to run behind his blockers -- he sees the hole really well. He's consistently, throughtout his career, made people miss once he gets to the 2nd level. He's also a solid receiver out of the backfield, look at his career stats. He's also a decent blocker. At the right price and Patriot style supervision as well as a low risk contract he's worth a look. He's not as good as Dillon was when the Pats acquired him but he can be a productive player in the right situation. I think the Pats have proven that they can handle players like this guy. I think the Pats would have some level of interest, players with his talent level don't ususally become available this time of year.

I don't know about any knee injury but he's had neck and foot issues in the past.
