Being selfish (after all, my name is Self), I'd love to see him stay. For his own good, he needs to go. He's not superhuman. One chop at his knee and his career could be over. He's given us more than enough...
No argument here...he has provided his teammates and the Bama faithful with something we haven't had much of in a long time (MI notwithstanding). He doesn't owe anything to anyone but his family.
Let me correct that (since he got the record for most rushing td's in a year)...ever.
