Margarito. Algieri. Rios. Margarito and Algieri both took beatings and could have EASILY been TKO victories. Rios took a sustained beating that he never recovered from and has looked like hot garbage since.
His situation is probably similar to Povetkin's — at certain age a fighter loses his hands' speed. Just milliseconds maybe, but that's enough for his opponents to see the incoming punches (that used to come "as a surprise" when the fighter was in his prime), so less and less knockouts...
Margarito and Algieri and Horn, doe. No one would have complained of the ref had stopped the fight. And Rios.
Pac is a changed man, when he became a Christian, he became a humanitarian, maybe that's the difference
Alfieri was actually down for the full ten for one of his knock-downs but something happened like the ref picking up the count wrong iirc. Either way he just isn't a KO artist at WW, fighting guys mainly who are bigger than him, power has depleted some, the chins are better at the higher weights and he also changed more into a boxpuncher than an out and out aggressive swarmer. Still, can punch though, he wobbled Floyd, near had Horn out on his feet, had Mosley asking to quit, Algieri, Rios and Margarito copped beatdowns and Clottey didn't want to throw a punch. Marquez was also badly hurt in fight four but he had an equaliser in store. He even hurt Bradley a few times between there fights iirc. Dear La Hoya, Mosley, Cotto, Floyd, Bradley, Clottey, Hatton, Vargas, Rios, Algieri, Horn, Marquez are the guys he fought above lightweight and when he fought them they had combined stoppage losses of two I believe so some granite chins in there.
