Mavs Owner Cuban Mum About Interest in Cubs

Now that the team will be for sale after this season, might the billionaire owner of the Dallas Mavericks step up to the plate and put in a bid?

Cuban says he doesn't know yet.

His comments come one week after the announcement of the planned sale by Sam Zell. He's the real estate magnate who is buying the team's parent company Tribune Company.

The Mavericks have gone from one of the N-B-A's worst teams to one of its best during Cuban's ownership.

While he rubs some people the wrong way, his energy and cash have been a big part of the club's turnaround. That's prompted fans of underachieving teams from across the country to e-mail him about buying their team.
