Mark Cuban couldn't help but taking a jab while congratulating ex-Mavs coach Don Nelson for breaking the NBA's wins record.
"And congrats to Nellie !" Cuban tweeted. "I feel like the guy who paid for a 3rd wedding. Happy u r now happy"
Rough translation: Nellie, now that you're basking in this historic moment, this is a good time to remind folks that you quit on the Mavs.
