BASEketball (1998)

Two losers from Milwaukee, Coop and Remer, invent a new game combining basketball with the rules of baseball. When the game becomes a huge success, they, along with a billionaire's help, form the Professional Baseketball League where everyone gets the same pay and no team can change cities. When a rival owner wants to institute major rule changes, Coop and Remer's team is the only one standing in the way.
