I don't blame Oscar in the least. The sooner he can get away from Calipari, the better. He was a outstanding college player with some flaws. Now we see just how strong his desire to succeed in the NBA really is. He'll never be a star but, he could be a nice sub or role player for a few years.
My guess is he will have a cup of coffee with two or three teams in the league and then end up over seas making really solid money.
Best of luck to the big guy!
