In terms of p4p legacy. Leaving aside the size of the event, cultural impact, all that and purely focusing on sporting legacy. Duran-leonard I? Armstrong-Ross? Charles Walcott i/2? Ali-foreman? Others?
Ali/foreman is huge I've heard the claims that Leonard was green for the first Duran fight (which is debatable imo), but it's still among the best ever. Leonard against Hagler deserves a mention
Fuck judging corruption, whitaker's win over chavez would chart top 10-20 (diminished somewhat by the weight)
It's not quite on the same level as some of the previous ones but Jones-Toney deserves a mention. I don't know which fight, but Pacquiao has plenty to choose from. In terms of jumping way up the P4P list from a single victory you have Mosley-ODLH. For just once choice I'd probably go with Duran-Leonard.
Probably the 3 time champ randall bailey icing the formidable bolillo gonzalez in under a minute for his first belt
Juan Manuel Marquez knocking out Pacquiao. Pacquiao beating De La Hoya (yeah...De La Hoya was old etc...but Pacquiao was a former flyweight!!)
Frazier-Ali 1 Duran-Leonard 1 Ali-Foreman Leonard-Hagler Hopkins-Trinidad Turpin-Robinson 1 and 2 Louis-Schmeling 1 and 2 Pryor-Arguello 1
In hindsight it wasn't all that much of an accomplishment. Hopkins was bigger and a dominant 160lb champ and Tito was a former Welterweight that had been dropped repeatedly at lower weights and out boxed for much of the fight against De La Hoya and David Reid.
It was a good win but I never thought as highly of Tito as others did. The hype around the guy before that fight was absurd, I remember Ring Magazine saying he'd knock out Hopkins and then outpoint Roy with his "underrated jab". Never understood it.
But that makes it a very pivotal win - Hopkins seized all that hypebin one night and became "the" man overnight.
Funny thing about this is if he hadn't had to retape his gloves, trinidad probably would have won. As it were, he had to load up twice as much, got tired, and still couldn't do shit to hopkins.
I don't subscribe to the loaded gloves thing but even if it were true it wouldn't have made a difference, the guy barely landed anything. Hopkins was just too good for him.
