DALLAS -- Sweat wasn’t the only thing dripping from Mark Cuban during his customary pregame workout on the stairstepper Tuesday night.

The sarcasm poured when the subject turned to Derek Fisher signing with the Oklahoma City Thunder a little more than two months after requesting his release from the Mavericks for family reasons.

Cuban, who said there was “no side deal” regarding family issues when Fisher signed with the Mavs, sarcastically claimed he understood Fisher’s decision to resume his career with a contender.

“His kids are older,” Cuban said. “It’s easier to fly in and out of Oklahoma City than Dallas. I understand that. It’s a decision a parent has to make. Every parent has difficult decisions to make.”

Moments later, Cuban added: “A lot can happen in 65 days.”

This marks the second consecutive season that a former Laker has quit on the Mavs. Unlike Lamar Odom, Fisher at least had the decency to stop cashing paychecks signed by Cuban.

Asked if he planned to stay away from ex-Lakers, Cuban said, “In protection of my [Twitter] timeline, I’m not going to say anything.”
