I do not know anything about him, other than there were some character concerns. While I do not know what you mean specifically, it is believable. He probably won't get drafted iif that is his rep.
Lets just say, he would be a perfect fit for the Raiders
a few hours after Ga. Southern lost to App this year, he was arrested for for a fight at a bar and during the semi-finals game against North Dakota St. he tried to start a fight on the field after the game. he also gets a lot of 15 yd flags
that was just this year, so i'm sure there are more examples in the previous 3 years
