From the games I have watched Gillislee play RB, he is an NFL RB. I would draft him in a heartbeat. I think he could be a really good player in the NFL.
I've watched every Florida game this season and after the first few games I would totally agree with you, recently though he's not been as impressive, that might have something to do with the average play of the OL though. In the mid rounds Gills may be a heck of a pick up. The fins probably don't need another RB, even if we don't resign Reggie, but if things change and it becomes a need would love to see us use one of our 3rds on Mike.
