Jordan Scarlett had issues as a freshman.... seems to be doing ok.
Look, I don't know if Thompson will get better or not, but remember he was a WR who moved to RB as a soph. So, he only had one season of juco coaching when he arrived on campus.
He was also a guy who lost the ball extending too much trying to get that extra yard or two. Omarius Hines was like that too. Sometimes they have to be coached to just go down rather than get out of control or get held up and hit by multiple dudes some of whom are ripping or putting their helmet on the ball.
