Mayweather: Not the first boxer to say one thing and do another

This is about his prediction to knock out Pacman- I think this is a Bluff. Personally think he will only go for a Ko if it presents itself. I dont think this will happen and think Floyd will be content to frustrate Manny during the first 4 rds, take away his left (look how Floyd positions his feet) and then build up his punch stats from then. UD to Floyd (with the support of Vegas judges)
