Oh, Duhon likes to shoot... He's just always had teammates who liked to shoot more! The whole reason why he moved to NY was because he thought he should have been starter material in Chicago (following the guy he was supposed to have replaced on the Bulls, Jamal Crawford, who liked to shoot more than Duhon...) I think it was Ben Gordon who finally convince Duhon that he'd never be a star in Chicago.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
