If Mayweather fought anyone in the UFC at the same weight class I would have to take Mayweather once someone shoots for his legs they would get hit with an assortment of punches to the top of the head. Shooting at someones legs with your head down is not intelligent fighting.
r arms longer than legs? do u seriously think legs can't move as fast as arms? watch this video and tell me if u can land a punch on this dude's face before he lands a kick on ur neck. folyd will have a very hard time landing a punch on this dude.
