He also has good timing in his pitches--not too early in a way that doesn't fool any of the pursuit, but not too late where the back is going to run into the same wall the QB will. A very unselfish style of play because the QB with good timing on the option often gets hit pretty hard by DL's and LB's in pursuit. Gregory has shown himself to be among the best option QB's in terms of timing I've ever seen. He does not have the absolute power that Ell (sure miss that guy) Roberson, but has better pitch timing.
Really all this says to me is that Grant Gregory has the ability to be coached because let's be honest he has to run the option this way or it would never work for this team. As for Ell, he was "selfish" and did not have textbook timing on pitches because he could take the ball to the house at almost any time on the field. Having a QB that can run with the ball is what makes a good option team. Gregory has shown the ability to make the right decision and play within himself - which is all it takes to get on the field at QB this season. I'm not trying to hate on GG, but I'm not going to say he runs the option "really well" yet. If GG was in the backfield w/ Keithen Valentine, not DT, would anyone be close to saying he runs the option "really well"?
I agree w/ the poor man's Matt Miller comparison for GG... 
What the back does after the toss is up to the back, and isn't Valentine at or near the top of the conference in yards per carry?
True, it is up to the back, I'm just arguing that our perception of how GG runs the option is partially a consequence of what DT does.
Valentine's yards per carry is irrelevant considering most of those carries were against inferior opponents or during blowouts - 11 v. UMASS, 10 v. Tenn Tech, and 10 v. A&M.
His yards per carry would be considerably lower if he were playing as much as DT and in the same situations. Although, if under 50 carries qualifies you, Keithen would be near the top as he is averaging over 7 yards per carry now (on 46 carries).
Agreed on the quick pitch point regarding GG, reminds me of some of NU's QB's - Frost and Crouch...
