Business decision. The guy wants to play in the league for a few years and UNC is producing NFL RB's lately.
My opinion on a lot of these transfers is that UT was a mess and the one time transfer rule and the extra year of eligibility gave these kids an opportunity to get away and have a fresh start somewhere else. I really can't blame them. With all the drama under Pruitt - paying players, firing coaches at halftime, the QB situation, and more - I imagine that locker room being a toxic place for a level headed athlete. It makes me think of the movie "The Program."
