Hurd is a guy who has a hard style for many guys to deal with. Hes big and he has excellent stamina. He wears guys down through sheer exhaustion until he dominates the cards from the 8th round on or he scores a late KO. But he doesnt have much power or skills. Harrison is a very good fighter, but hes a finesse fighter. You put the pressure on him he is right there to be pressured and overpowered. Which is what Hurd does. And Lara is a pretty good defensive boxer. But he was 35. And was just too old for that kind of war of attrition. Same with Trout just too old to keep up that kind of a fight. But against JRock he was fighting a guy who was 29 years old. And has good conditioning. You kept waiting for him to wilt and breakdown from exhaustion. But he just didn't do it. His conditioning and physical strength was just too good. And once you realize you can match Hurds stamina and strength, then stylistically there isnt much left he has to offer.
