The OKC NBA team picked up DMase in a 3 team trade, detailed here. Personally, I'm glad to see it, because I really like Mase as a player and as a person (got to know him a little bit while he was here with the Hornets), and it takes Luke Ridnour out of the mix in OKC. Don't ask me why, but I have never liked Ridnour.
OKC also gets Joe Smith from Cleveland.
I know Mason was an aggroid, but if you know anything about his background, he has a pretty inspiring story. Plus, he busts his ***. Glad to have him back.
