With only two more practices remaining before Saturday's spring-ending Gold-Blue scrimmage, the workload on both Alston and Buie might be reduced.
Again, with only two healthy tailbacks - Garrison is expected to return for fall camp - why beat up the ones who are relatively healthy?
Fullback is another matter. Not only is Clarke the only experienced player at the position, he's been hurt and may not play at all in the Gold-Blue game.
"Unfortunately, he got his ankle hurt last week, but I think we saw enough of what he can do,'' Gillespie said. "He definitely got better this spring. Hopefully, he can get better and participate in the spring game, but if not he definitely made strides and will continue to get better. His fundamentals are very good and he's had a phenomenal spring so far.''
With Clarke sidelined, Miles has gotten a chance at some practical experience at his new position. He wasn't likely to play much as a linebacker after four years of trying, but now he's on a very short list of fullbacks.
"Donovan has done a really good job. He's a very unselfish player and an older guy,'' Gillespie said. "He just wanted to get on the field. It was something that coach [Dana] Holgorsen and the defensive guys tried to figure out - who was a bigger body that they could stand to lose, and right now we have some younger guys at linebacker. Donovan was really willing to come over.
"He's done a really good job, just because he wants to play football. He wants to get on the field and it matters to him. He's done a really good job. I'm glad to have him.''
