He's at the pinnacle of his career and he's making the money that he wants to make, so there may not be a reason for him to be as wild as he used to be.
Oscar: It's clear that Floyd cant stand him, and Im sure the feeling is mutual at this point. He got past Oscar in the biggest fight of his career, so Im sure that monkey was off of his back in regards to making a big step in his career.
Hatton: Hatton just talks shit naturally, so it was pretty easy for Floyd to engage in it.
JMM: No reason to really go at JMM, other than the drinking the urine incident
Mosley: He sounded off on Shane for all the right reasons. Shane was nearly begging for a big payday, and was nothing more than an "ass chapper" around that time. He had ties to De La Hoya as well, so that gave Floyd more reasons to trash talk.
Ortiz: There was really nothing big to go at Ortiz about. Well, maybe it was, but floyd did his best to make sure that Ortiz remained a credible opponent, so it seemed like he cut down on trash talk. Better yet, he saved it for the winding down time before the fight...more like a week and a half before the fight date.
Cotto: Not much there for him to trash talk Miguel. If Mayorga couldn't get Cotto out of his element, then I dont see how Mayweather will be able to do so.
