Mark Cuban has attempted to purchase a Major League Baseball team to add to the Dallas Mavericks, but he has never been connected to the National Football League.

"I can't afford an NFL team," said Cuban.

Cuban is believed to have a net worth of approximately $2 billion.

The Dallas Cowboys are the NFL's most valuable team at $2.3 billion. Jerry Jones is worth upwards of $3 billion with the Cowboys as his biggest single asset.
