So Cuban, and Cuban alone, is responsible for the personnel decisions on the Mavs, and would be if he bought the Cubs? no, but only jerry jones has his hand further in the cookie jar than mark cuban. Okay, let's assume that Cuban has a lot of influence over these things. He took over a team in January of 2000 that ended up finishing 40-42. After that: 53-29 57-25 60-22 52-30 58-24 60-22 67-15 That's a .709 Winning percentage in the more difficult of the two conferences. He's not running the team into the ground. The exact opposite, actually. Ding, ding, ding! We have a winner! Cuban has consistently put the Mavs in a position to win. He would be a first class owner.
