He comments on this today at his blog:
In summary, this team still has not beaten an above .500 team since the Jason Kidd trade. And since I mentioned Kidd, could we point out that he had 1 point, 3 rebounds, and 7 assists in a critical contest? Is there still talk of him being Dirk's equal for leading this team? I guess I expected his stamp on the game in much bigger ways. I also expect that Mark Cuban feels the same way.
If Cuban does feel the same way, isn't it about time he starts taking a hard look at his coach and de facto g.m.? If this team flames out again, I'm hard-pressed to understand why Avery should stick around.
