one of his biggest issues as an athlete is that he is undersized, and this has nothing to do with his off the field issues. Some undersized players can outrun or make defenders miss, it seems to me that he gets hit and knocked backwards allot. He very rarely avoids or can even elude DB's much less LB's. I don't think, even if he were the perfect student athlete off the field that he would succeed at the FBS level. I think he can be a very serviceable player at the FCS level.
Just my opinion.
