"Arizona's Derrick Williams raised a few eyebrows at the NBA Draft Combine in Chicago last month by stating he could play either forward position.

The Cavaliers really aren't sure that's the case, and they have plenty of company.

"He doesn't have an established position," ESPN's Jay Bilas said in a conference call with reporters last week. "He's kind of in between a 3 and a 4."

Because he is neither a guard nor a big man, Williams is the top wing player in Thursday's NBA Draft. But he is not really a wing, which is too bad since the three teams with the top four picks -- Cleveland, Minnesota and Utah -- could use one.

ESPN's Chad Ford thinks that may be one of the reasons Williams insists he can play either forward position.

"Part of this is just the salesmanship that his agent's been working on with him to convince teams that he could play this position," Ford said, referring to agent Rob Pelinka. "If teams were just drafting on need, you look at those teams and [a 4] is not the biggest need for any of the top three teams in the draft, and that is a problem for Derrick Williams."

This is not to say Williams won't be a good player, and he likely will be taken no lower than No. 2 if the Cavs don't make him the No. 1 pick.

"He is going to be a really good NBA player," said Bilas, who broadcast a lot of Arizona games last season and watched a lot of tape of Williams."
