I'd bet what he TRULY wanted to do was go straight to the NBA. That's true of all top 20 or so recruits but they can't, so they make "business" decisions.
True, he'll spend one year in college and really won't affect Kentucky fortunes much at all. Otoh, going to Arkansas would have had a much greater impact, if nothing else on recruiting. I don't wish him anything, good or bad, but I do wish the whole subject would go away already and just move on.
