I like two Texas guys, Damion James in the 1st and Dexter Pittman in the 2nd.
James will be a solid wing player that they can play groom behind Pierce. Pittman sounds very similar to Perkins and would be the perfect future back up for the big man.
I like all the Texas guys, including Bradley.
Damion James would look very good on this team and not just as a wing but as a Posey/Marion-esque 3/4. Only 6'7, but he's got a 7'1 wingspan and a better standing reach than Shelden Williams and Blake Griffin. Good athlete, excellent rebounder, accurate shooter from deep and from the mid-range, decent ball-handling skills, has played the 3 and the 4, plays solid defense, an excellent weapon in transition.
Pittman is fatter than Perk ever was, but he's got much better touch. Hard to see him making it in the league unless he drops some serious poundage though.
Bradley's really quick with the ball, good defender, good shooter. I think he could play alongside Rondo in a small line-up.
