Mayweather will attempt to KO Marquez

[Majesty]

Floyd has come out swinging plenty of times, I don't think he will, but the more this is a war IMO the worse it is for Marquez because Mayweather stays so sharp late in fights, he is still sharp even when he is throwing down, and he will getting hit a lot less than MArquez.

When? I can't recall a time he has come out the more aggressive fighter. He is never so careless as to come out swinging.

It depends what you consider swinging, but against Phillip N'Dou, Burton, Sosa, Gatti, G. Hernandez, plenty of guys earlier on in his career.

Mayweather fights the style necessary to beat whomever he is fighting. If he knows he can't impose his will or beat them by slugging he won't do it. But if its someone he can impose on he will. He is a fighter who has an uncanny ability to adapt.
