I love this signing. Some folks on here may remember how badly I wanted KBD in the draft a couple of years ago. I was heart-broken when he got taken right before the Spurs could get him in the second round. Part of why I was so frustrated with Metu is because he was the player the Spurs took/had to take instead. I don't know that he's going to be a long-term piece, but I'm happy SA saw the opportunity to snag a defensive combo-forward and went for it.
EDIT: I went immediately to the bottom of the thread to post. I can see that a bunch of people agreed with me on KBD. It's cool that we'll get to have our wishes fulfilled. Now if they could just somehow trade Sam for Clarke...
