Mark Cuban recently posted some thoughts on "NBA Sabermetrics" (he termed it "sabremetrics") : BlogMaverick
It is interesting coming from him, considering he has previously been a proponent of "APBRmetrics" or "NBA Sabermetrics". I think it does stem from his frustration of the inability to form a championship team in Dallas, but he hasn't done bad. A large part of the problem is trading for older, past prime players, a la, Shawn Marion, Jason Kidd, etc.
Sabermetrics work much better in baseball because there is very little "teamwork/play/chemistry" in baseball, it is very much a 1 on 1 game. Basketball is much tougher because you cannot just replace a player and the team won't miss a beat. Compare swapping Albert Pujols with Ryan Howard and Derick Rose with Devin Harris.
Anyways those are just my initial thoughts when reading the post. Feel free to tell me I'm a fool.
