Is it just me or does Cunningham seem to get himself involved in a lot of important plays, even if doesn't count on the stat sheet?
When I reviewed Florida's games last year, one thing that stood out was how consistently Cunningham was getting pressure. In the games I saw, he was probably getting more pressures than the rest of the team combined (Carlos Dunlap is 3rd string at the Bengals, BTW).
He almost always relied on his excellent first step and size and speed to run around the OT. I'm glad to see him developing some inside moves with the Patriots (he got good pressure on Sanchez that way). On the play in question, he at first seems startled and hesitates when the OT leaves him to the back, then accelerates and demolishes the back and arrives at Fitzpatrick just as he is releasing the ball.
However he screwed up run contains horribly twice on Sunday, and was benched for TBC for a while after the second incident. The good news is that they were both technique errors so are hopefully correctable. To my eyes, he is visibly more talented than TBC, Ninkovich, or Crable: bigger, faster, stronger. There's still hope for him to develop into something special.
