Mark Cuban hasn't forgiven Jason Kidd for leaving the Mavericks for the Knicks last month. He says that J-Kidd was thisclose to signing a three-year deal with Dallas in early July when Kidd suddenly switched gears overnight and decided that he wanted to sign with New York instead. As a result, he said he's not going to retire Kidd's jersey number when he retires.

"I was more than upset," he said during an interview on ESPN Dallas 103.3 FM earlier today. "I thought he was coming. I was pissed. J-Kidd is a big boy; he can do whatever he wants. But, you don't change your mind like that. That was…yeah. I'm sure I'll get over it at some point, but as of now, I wouldn't put J-Kidd's number in the rafters…It hurt my feelings, period, because I felt that we had developed a relationship, and I thought that he was committed to the organization. It sure seemed that he was. I mean, J-Kidd was active in going out there and talking to Deron Williams the whole time. I guess it was more shocking and surprising than anything else."

It was business, Mark. You, of all people, should know that.
