I'd do the 2012 pick though. I think there is a chance the CBA adds a year to eligibility, so 2012 could be a "dead" draft with no elite freshman in the draft, our pick would probably be better, but that would be our last year of this squad as we know it, so probably a low pick too, and the team may be active in trades that year with ability to pick up some picks etc.
Brewer could really take off on this team - he'd basically get Tony Allen's minutes, but he's capable of hitting wide open corner threes. He can't handle the ball, but with Nate coming back that's a good tandem at the wings/guards off the bench. He also has some ability to make another leap so it's a good gamble.
The only down side is his salary spot might make it hard to keep him if we sign a FA in 2012. But that's a small gamble.
