I think Floyd matured his boxing style into what we saw in his last fight. He didn't stick and move and stay with a jab all night to cruise to a comfortable decision. No, he did something that majority of his critics said he wouldn't do...be the pressure fighter and push the offence. Mayweather didn't sit on the back foot instead he sat flat footed toe to toe with a man who has KO power. To me it was exciting now don't get me wrong I think watching Floyd period is interesting based on my love of the sweet science of boxing. But Floyd that night brought an offence that we haven't seen since the Gatti fight. Some say it's because Floyd wanted to be the first to KO Shane, others say it's because the critics said he runs too much, and I would say is because he wanted prove that he can make a fight exciting in the ring.
He used a turtle shell/peek a boo mixed with ear muffs defensive stance to trap and bait Mosley in for a sweet counter left hook to neutralize Mosley's feint's and weak jabs. Or the classic pull counter when Mosley tries to go for the head too easy. Mayweather's style is an enigma, Shane thought Floyd wasn't going to be the one pushing the fight he trained to bring the fight to Mayweather which played to Floyd's hands. I can tell if Mosley didn't have the chin he had he probably would have gotten KO'd or TKO'd. Mayweather was throwing more shots than 3 of his last fight combined in that 1 fight(joking) but seperate yes. In round 10 he was close to putting down Mosley as he hit him with a nasty bodyshot that had Mosley off the back foot for the rest of the round.
I would love to see this style more often in his future fights. I'm not sure if it would be wise to use this style against someone like Ortiz but we'll see. Floyd shocked many with that type of performance and since he adapts you'll never know which Mayweather will come to box or bang.
P.S. I am aboxing fan first, Floyd fan 2nd.
