Butch Jones also put a stop to signing athletes that can compete at a championship level. If you recruit hulks, you will inevitably get hulk behavior. It's just a matter of keeping control of your program.
This player is a hard pass. It would be only a matter of time before we hear about him knocking out some frat kid at Cool Beans because he looked at him the wrong way. I'm all for second chances, but this kid needs to go the Juco route and prove he's worthy of being a collegiate athlete.
I would give the kid a chance knowing that its his last chance. Maybe make him redshirt this year to get things together. Also I would expect that he would give his all for Tennessee especially against Alabama.
