2 things:
#1 What does Kemba have to gain by performing against Jimmer? Actually, what does even Jimmer really gain by performing against Kemba? Both aren't exactly Lebron James. Neither is perfect and both are fighting to be drafted in the lottery. Why play each other?
#2 Why do so many here apparently think that Kemba will have a better NBA career? Kemba is a SG. He rarely handled the ball at UCONN, especially in tight situations. As Locke said the other day, Kemba will need to DRASTICALLY change his game to survive in the NBA. He came off picks, he shot the ball off cuts and curls, he plays like a SG. Jimmer, while needing to develop more PG skills (he improved drastically in getting other guys involved and ball handling from just his junior to senior years), can already do many things that Kemba cannot. Plus, his shooting will never need to be adjusted.
If given the choice between the 2, I'd take Jimmer. At least I know he can shoot the brains out of the basket. At least I know he can be counted on to nail a few 3s from 3 feet behind the line. At least I know he won't be a liability at the FT line. With Kemba? How do I know he won't be out of this league in the next 3 years? He won't be able to drive and score inside with his size. I know he won't be able to play the point real effectively. And I know his shot sucks.
So what does Kemba bring to the table exactly? As I've said before, he's UCONN's version of Mateen Cleaves. Great college player, poor NBA.
