Mark Cuban is one of the best owners in sports, period. he is a guy committed to winning and passionate about the team. Sometimes, I have questioned his moves and tinkering with the team, but in the end, he is a very smart guy and he is a great owner.
I dont see much hate about him as an owner. People get turned off by his cocky personality but everyone knows he is a great owner.
He has owned the team since 2000 and every year he has been owner, they have made the playoffs AND won 50+ games. And 2 finals appearances. I would have to say, to accomplish what he has in 11 years is remarkable.
