9. Ethers Shane Mosley
Craziest Line: "Shane Moseley...a guy who's extremely desperate."
After defeating Juan Manuel Marquez, Mayweather was asked about his thoughts on facing Shane Mosely and he didn't hold back. Floyd said Sugar Shane was a desperate and washed-up steroid user. Of course, the script flipped later on when the Mayweather v. Mosley bout was set and promoted as an intriguing match-up. Gotta love boxing.
