He was a free agent and just agreed to go into the D-League to attempt to showcase his abilities again. His defense isn't great, but the dude can flat out dish the ball (http://www.youtube.com/watch?v=tqe-13YOcIU).
He was drafted 16 (!) spots ahead of Teague in the 2011 draft, and Phoenix threw him into the Gortat deal just so Washington could cut him. As a Kansas Jayhawks fan, I remember when he broke his wrist and couldn't play in the elite 8 against KU. I remember thinking how disjointed his THREE fellow all Americans (all of whom are now decent NBA players: John Henson, Tyler Zeller, and Harrison Barnes) looked without him on the floor.
I'm not saying he's gonna come in and light it up with 10 assists a game, but he's only 22, and he couldn't possibly be worse than Teague behind Hinrich, and who knows, maybe he surprises us and ends up starting by the end of the year.
