Earlier this season, Derek Fisher asked Mark Cuban to release him from the Mavericks so that he could spend more time with his family. And, Cubes agreed to do it, because he wanted to help the NBA veteran out. So, you can imagine how disappointed the Mavs owner was when Fisher agreed to a new deal with the Thunder just a couple months later without even bothering to call him about it.

"My personality is to try to help somebody, particularly someone that I thought one thing about, even if it didn't turn out to be that way," Cuban said. "So I was just trying to be nice and help. Usually when you help somebody, you expect at least some semblance of loyalty back. When you don't get it, then it's more disappointing."

As a result of his disappointment, Cuban—and the thousands of fans in attendance at the Thunder/Mavericks game last night—booed Fisher last night. And, after what happened, can you really blame them?
