Brown is miles better then anyone Floyd took on at 147. His size, physical style and power will give Floyd a very hard fight. But I think he is a tad to limited compared to Floyd to make this work for him...I see Floyd winning some clear rounds with clean punching and neutralizing Browns offense with movement, but I see him over the course of the fight playing it safe and mostly eeking out rounds. Floyd's style would give Brown some trouble I imagine. Probably not a hell of a lot in it by the final bell if the judges like Brown's aggression, body work and powershots. Brown showed, especially earlier in his career, pretty good skills at range. He would be almost considered a boxer puncher..if it wasnt for the fact he looked a bit one dimensional later on...probably because his opposition stepped up. I say Mayweather in a non-controversial SD.
Brown was a good fighter, but had a bit of the dog in him, when it came to the top opponents. I see Lil Floyd dominating him with speed and movement and Bruno just going into just glad to here the final bell mode. Mayweather WU12/15
