You could apply this quote to half the teams in the NBA right now (Lakers, T-Wolves, Magic), but you're right. It takes a special kind of ineptness to get called out personally by the Commish. Of course, you can hardly blame the guy for lashing out, considering he had to hear about Zeke's sexual harassment suit while he was in the middle of dealing with the Tim Donaghy scandal.
I just saw today that Ellis was gone. All I've ever heard about Mayo is that he and Walker are a package, but all I've ever "heard" is Internet gossip, though I do believe they have the same legal guardian.
