nah PBF has great endurance, when have we ever seen him tired? never. He spars for 15 rounds and in the Hatton fight you could see how fresh he was after a grueling inside fight while Hatton was very tired and Hattons whole plan was to be the guy with the better stamina. I dont think JMM at 36 will have better endurance than PBF. PBF works hard and has great genetics, you can see his uncle and dad who eat a **** diet from what they say and are still in great shape for 50 year olds.
I've really warmed to him recently, when he rolls the shoulders and dodges it's truly amazing to see him evade punches. :thumbsup He will destroy Marquez to send a warning to Pac and Cotto.
