FILE - In this Dec, 10, 2012, file photo, boxer Floyd Mayweather, Jr., watches an NBA basketball game between the Miami Heat and the Atlanta Hawks in Miami. Mayweather Jr. won't know until halftime which team he'll pick to win the national basketball championship. Once the undefeated boxing champion figures it out, he is expecting to place a $50,000 bet toward either Michigan or Louisville in the NCAA college basketball title game on Monday night, April 8, 2013.
