Roach is just talking out of his ass here. Mayweather didn't use his movement because he didn't want to give Mosley the chance to get the ball rolling with his feet. He wanted to make Mosley fight flatfooted on the outside3 which he knew Mosley wasn't very good at. I don't even think Floyd was that aggressive, I just think he was standing his ground rather then potshotting. He seemed to be carrying his weight on his front foot which was a bit odd I'm not sure I've seen it from Floyd before.

Roach is just goading. I will say this though, that right hand Mosley hit Floyd with wasn't just a right hand. He blinded him or at least distracted him with a jab to the body and then was able to wing a right hand over that. That's very similar to what we have seen Pac do time and time again. That was kind of interesting.

Roach is very annoying though. To bad Nazim couldn't train Pac.
