I hope you guys realize that the reason he didn't put up the numbers is because he was injured. The problem with him is staying healthy not talent, he has NFL size and speed. If he can stay healthy he has all the makings of a star.
The guy played less than 4 games this past year what kind of stats do you expect from him? He started the majority of the games he was healthy for his freshman year.
41 tackles and 4.5 sacks in around ten games while dealing with injuries is not too bad and would be a worthy addition.
