Funny thing is, Floyd is one of the great ones too and sharp as a tack. He’s just a buttwipe. Manny is a great one too. Mayweather doesn’t want to fight Manny and ruin his perfect record and he’s trying to cover up being afraid to lose. He even made Marquez agree to fight him at 5 or 6 overweight. He knows what’s doable and what’s not - Pacquiao isn’t doable.
Mayweather has one of the biggest scams going -- he makes sure that any opponent of his first bust their butt fighting guys he would never face himself. Then after his opponent has been through so many ring wars, then and only then does Mayweather sign on to fight the guy.
Even if he were to beat Pacquiao, none of what he does equals what Manny has done, unless Mayweather beats the top middleweights, super-middleweights, and light-heavyweights today.
