Derek Fisher signed with the Oklahoma City Thunder this week a few months after leaving the Dallas Mavericks citing an injured knee and desire to be with his family in California.
“He and Mark (Cuban) had an agreement when he came here that he would come and if things got to where he needed to leave for family reasons, he would do that,” Rick Carlisle said. “That’s what he said was the situation. I’m going to take him at his word.
“Look, he’s one of those guys who have been around this league for a long time. He’s won a lot of rings. My opinion is he’s earned the right to do what’s best for him.
“If Oklahoma City’s a good situation for him, then that’s what he should do. We’ve got to carry on. We can’t be concerned about things like that.”
A league source told Jeff Caplan of NBA.com that the Mavericks' front office was "agitated" by Fisher's decision.
