I agree with PMG -- had Stith transferred to one of those lower D-I schools, he could very easily be putting up good numbers (or do so in the future). Malik is very fast and athletic, and would probably be one of the better athletes in those teams/conferences. I don't fault Ty or Q for transferring, but kudos to Malik for wanting to compete against the best. I hope he has a few moments in him this year, provides leadership/intangibles (in addition to minutes), and develops his game so that maybe next year he can contribute a bit more.
Also, I think Roberts is a different animal than the other two, as he seemed to be recruited by bigger and better schools.
