somebody talented dynamic offensively i.e. pacquiao could do it. a good boxer with good fundamentals who can break down his style with intelligence could do it. a rangy / tall fighter with good boing skills would always give him problems. a tough infighter/ volume puncher with smarts like a duran could do it as well.
have to cut the ring off and hit hard and pound him on the ropes or in the corner....sergio is prob the only guy out there who can do it at this point
Taller Fast hands High punch output Good stamina Adaptive skills In my eyes the guy tht beats Floyd must have all of these, but he must also be able to change his style every 2 rounds to keep Floyd from getting settled.
It could be Sergio Maravilla but i'm not 100% sure that he could "annihilate" Floyd style. Pacquiao , don't think so . Amir Khan would give Floyd some problems in the ring. To beat Floyd Mayweather , you have to be smarter/cunning than him and of course to have some good skills.
A guy who cuts off the ring and tries to pound his opponent on the ropes or in the corner doesn't fit the bill on how Martinez fights. Just saying.
