Where does Arizona star Derrick Williams rank among pro prospects? Right at the top, according to Steve Kerr.

Kerr said Williams was "not on the Kobe level" but would be a 20-point average NBA player.

"He’s probably a top five pick looking at this year’s draft, and it’s tough to pass up that kind of money," Kerr said. "But every player has to develop his own desires and needs. If money is an issue then he should come out. On the other hand, Sean Elliott stayed and Michael Jordan stayed until his junior year. Very rarely does it happen where a guy that highly thought of actually drops down but what did happen in the past was guys got better by staying and they had better pro careers. That's something they don’t think about.

"The only question is what position he’ll play," Kerr said. "A lot of people say he’s got to learn the three (small forward). I disagree. There’s a lot of smaller guys playing the four and he's versatile enough to handle the ball. So if you play him at the four, he can cause problems for people and he's so good around the basket."
