No idea, but I don't see him as the feature running back if he returns. He's not fast nor agile enough. I expect Speights to take the job - much greater versatility & agility.

I think the coaching staff also hopes Speights gets the job. However, IMHO, Scarlett has shown he is our most effective back. Consider Cal last year, when he ran like 10 straight times at the end to ice the game. Consider Utah this year. We are doing nothing on the ground, they put Scarlett in, he runs several times for positive yards. On one play that was supposed to go inside he jumps  it to the outside and makes 10 yards, rather than getting stuffed like we had been. So the coaches take him out and put Speights back in. From then on, nothing. Scarlett may not have the up side of the other candidates (in terms of raw speed), but up to now, he has played better with better results than the other guys. He also can catch passes, both screens and down the field, which the other backs have yet to show they can do.
I think he is the best back we have overall. He is not a CMac or Love, but he is effective. Some of the other guys may rise up and be better than Scarlett, but not so far. Scarlett is faster than he seems. He has "football speed" when he needs it. He for sure runs inside the tackles better than the other backs. He also is willing to break the play outside when there is nothing at the point of attack, which with our OL has been necessary more often than not. Against Pitt, I think some of the runs to the left were ad-libs on his part. It mostly worked. Therefore, I think he is our best back at the moment, and has been most of the year (Love being hurt). Speights runs more like Love, so it may be he was a more compatible backup, but as far as results, Scarlett was/is better, IMHO.
