LMAO you people are so funny, giving credit to what Berto says. He's full of shit and i'm shocked to see that people who know about boxing believe him.
You have to understand that the better your opponent is, the shittier you"ll look and styles make fights. Look when Pacquiao fought Marquez people said he looked like shit, forgetting about the caliber of opponent he had in front of him.
Mayweather MADE MOSLEY look like shit coz he dismantled him with his much superior SKILLS. Mosley fights Alvarez and you're gonna call him the terminator again.
