If we can get him, take Marcus Williams...He's the best pure PG in the draft, and shots well enough to help out on the perimeter offensively. He seems adequate defensively. He can sit behind Rafer for a year, and then start.
If he's gone, then Ronnie Brewer... He'll be a competent PG for quite a while, and he gives us a big guard to pair up with Luther Head, if Head does end up being our 2 of the future.
I was high on Rodney Carney, until I found out he only measured out at under 6'6" with shoes on...to small to play SF, and there's no point in basically duplicating what we already have in Head.
