Primera only lost once and he was rated #1 by a sanctioning body once, so therefore he wins by TKO over Oscar who was a loser
Plus Primera he was wrecked by Hearns, but so were Duran and Cuevas, which makes him as good as either one of them...plus he lasted longer than both of them combined, so when you use collegE matH that means he was at least twice as good as either of them. Anyone who disagrees couldn't possibly have gone to collegE.
