Manny Pacquaio
Manny Pacquaio and Floyd Mayweather discussed the possibility of a $50 million fight for years. But the two could not agree on terms and the fight never occurred. Pacquaio stock plummeted after he was knocked out by Juan Marquez in Dec. 2012. Although the knockout occurred at the end of 2012, it set the tone for a rather quiet year for boxing in 2013.
