Mayweather has primarily an outside style. Many people make a big deal out of Mayweather's defensive skills and they are pretty good, but not so good that he can't get hit buy even a slower opponent with less on the body movement boxing skills. If your review his fights it's because he gets swarmed or counter punched from his lead right. De La Hoya was not a on the toes style but a rather pressure fighter as was hatton. Both were guys that came straight forward and got to mayweather with swarms of punches but didn't give Mayweather too many angles to have to deal with. Marquez is going to give Mayweather some trouble but has problems cutting the ring as well as Hatton does. Marquez had problems with Chris John's deep in and out movements with just a 2" reach advantage and counldn't catch him. Mayweather will be able to exploit Marquez with his 5" reach advantage but will take some hits from Marquez because Mayweather timing is more predictable than Chris John's. Zab Judah was able to turn Mayweather and get in some good shots with his right hook, straight left and count left hook. Mayweather likes to duck and cover a lot, I think it's to conserve energy.

Fighting Pacquiao, Mayweather has three problems he has to deal with. First he has to deal with that southpaw stance which takes away alot of that reach advantage. Second Pacquiao has very good stamina and will have to deal with a lot of punches. Thirdly Pacquiao's speed. This combination is what will give Mayweather his first loss if he ever gets in the ring with Pacquaio. Even if Pacquiao can't get a clean knockout shot on Mayweather he's going to have more connects, and drive the pace of the fight to get a UD.
