Somebody do a photoshop of Blake's face and a Blazer logo in the Brokeback Mountain "I can't quit you" scene.
You do have to love that he was Patterson, Pritchard, and Olshey. Ironically, the centerpiece in each deal was a big man (trading small for big). Magloire, Camby, and Plumlee.
I think he has to be the only one. I'm not even sure any other NBA player was traded away twice from one team. It may have happened but that would be rare. And for Steve to do it three times? Well he'll be in the record books for something!
