Pernell was old and he got a gift against Delahoya. You forgot Benitez win over Palomino and his ko of Maurice Hope.
Benitez fought those 3 legends when they were all contending for titles. All 3 would win titles after Benitez fought them. Pernell was old. Hopkins was older also and the Jones fight was Roy fighting after being knocked out a few times. And also, those 3 of the fab 4 were greater than the other 3.
Cotto is not on that list. Those guys like Trinidad and Benitez (especially Wilfred) are in the class of Manny Pacman. Cotto is not.
