Do you see Dunn playing? The point or off guard?
I see him being the third guard...I see he, Posh and GWill being on the court at the same time, with a frontcourt of two bigs; Toro, Moore, Duke, Roberts. In away games, I can see him having more influence, familiarity with opposing arenas like Butler, Creighton, etc.
Like you said, if he still cant throw the ball in the ocean, its all a moot point. But because of his last season shooting woes, I would consider him a better candidate for most improved this season, as long as he worked on his shot in the off season.
