Floyd Mayweather has fought in every weight class from 130 to 154. And obviously hasn't been beaten in any of those weight classes.
A reporter asked Mayweather if he would willing to move up to 160 and fight Sergio Martinez, who beat Kelly Pavlik in Atlantic City recently.
Surprisingly, Mayweather said "it's possible". Mayweather, who has said on more than one occasion that he'd fight anyone, said he caught some of Martinez' fight against Pavlik.
"I though about that," he said. "It's possible."
If the "money" is right, you can bet "Money" will consider it.
