Sounds like although he wanted to come back, he must have received information that indicates he has a good opportunity to make a lot of money by coming out.
Sad to see him go but for him its the right decision after seeing Ridley and others success in the NFL. Although once again proves the "internet" is the single worst source of information. Between all the "recruiting" news (Bhelm excluded) and Hill returning posts on other sites that you might as well just make it up. Sometimes common sense makes the most sense. Why would Hill come back, did anyone think his stock would go up next year? Of course not we all love the LSU football program but if I was him and I can make big money, finish my degree later (See Shaq) so I have a life after football I would declare the first day I could.
I thought I read they show him a 3rd round pick..........from that standpoint alone, he would almost definitely improve himself. His off the field issues, will be issues with some teams, another year showing behavior consistent with what NFL teams expect would not have hurt him.
