I'm assuming this fight is taking place at 147. That is where Mayorga had most of his success, and that is closer to Camacho's prime weight. The problem with Camacho is that by the time he made it to 147, he had lost his will to compete. Camacho would still show up, and last the distance. Hector just showed no will to take the fight away from his opponents that were on par with his skill level. Mayorga would swarm Camacho several times a round, and have nothing to fear from Macho in return. Mayorga UD
