Margarito: You know you'd be in a tough fight, win or lose. A beating. And a guy with a Chin.
If you were tough enough, you'd survive the first 6 rounds and spit out blood and lose an ear!

Manny Pacquiao: You have to survive hell to beat him. Most likely you'd be KO'd.

Mayweather: Well... I take that back, only Gatti was afraid. haha
