"Charlotte Bobcats coach Paul Silas is glad his front office is investigating ways to move up in the June 23 NBA draft.

Still, Silas has misgivings about converting picks Nos. 9 and 19 into one higher pick unless they're sure that one player would have big impact.

"We've talked about moving up. My point is that if we do move up, that guy has to be a star kind of player," Silas said following the Bobcats' first pre-draft workout Thursday. "I think we'll get two real quality players here, to build on what we've established already.

Silas said he'd favor trading up "If the guy is someone we think can really help us. But he has to potentially be better than what we have now. And looking at this draft, I'm not quite sure that guy is there. If he is, then we'll certainly look at it."

The general consensus on this draft is it's short on star power, but relatively deep. Duke guard Kyrie Irving and Arizona forward Derrick Williams are expected to be the top two picks. While both are projected as solid pros, neither is expected to have the impact of recent high picks Derrick Rose of Chicago or Kevin Durant of Oklahoma City."
