He's a smaller fella, as you mentioned ... and he plays in the big ten. It's a conference that's hard on the body, honestly. Lots of cold games and close quarter contact. And he has had a lot of carries and hits.
I like him ... quite a bit ... as a college back. I think at the next level he's going to need at least a year to recover from his collegiate career. That said, if he runs a 4.40 I may change my mind ... but I have him high 4.5s by my eye tests (which are wrong about half the time, lol)
For instance, Sony Michel has basically never been the lead back at UGA. Rawleigh Williams of Arkansas ... LJ Scott of Michigan State ...
As far as a smaller back, Im thinking of Mark Walton on Miami, as he's dinged and not taking hits this year, and will likely drop to the 6th or 7th ...
