I think Small has 97% maxed out his physical development, and enjoyed a relatively injury-free season so far. I don't know how much there is left for him to learn and apply to the mental aspects of the position, but from what we hear, he's a leader and teacher in the RB room. All of which leaves him (IMHO) either NFL-ready after this season, or just not a Sunday prospect.
If the latter is the case, he stays on the team and takes advantage of his scholarship to progress academically toward his career goals. Or... if he has the potential and desire, and encouragement from the staff, he re-focuses on a coaching track and accepts back-up playing status to the up-and-coming young backs, while investing himself in their development--but now from a professional mindset.
Everything I've seen and heard about Jabari says that he is a high quality individual, the kind of person you want to invest in because he's going to create a positive future whatever path he chooses. And if that path keeps him inside the UTAD building another year or two---that's a win-win for this program.
