Mayweather knows that the way to sell PPVs is to play the role of the cocky bad guy. It's why he's been able to become a PPV fighter, whereas guys like Mosley and Hopkins never achieved that.

He's playing the role of bad guy again, but as people have been saying, he's been good-natured about it and has had a good time joking around with Hatton's fans.

I went to the Oscar-Floyd press tour when it was in DC, and after the press conference, Oscar left right away, whereas Floyd stayed for a while to sign autographs and mingle with the fans.
