My impression of Fields when he got here is that he may need development before he plays RB. Right now, he's tall and thin.
My guess is that we'll see Kevin Pope backing up Line before we see Fields. Pope already has the size, was faster than Line (although Zach improved his 40 time considerably, so that may not be true any more), and better fits the mold of a June Jones RB (bruising blocker) -- at least at this time.
I believe it was after the Bowl game that we all heard June hint about getting his best players on the field. That, among other things, is why I think we may see Fields at LB before we see him at RB.
Oh, and LeRibeus (last name spelled with an E) is supposed to be back. So I see him taking his left guard position back and Tennison moving back to center.
