The only time when the top 2 P4P fighters fought..

Yea, it adds a lil luster I guess. But I don't give a shit about the p4p thing.It's imaginary tbh. I just want the fight period.

You could make a case that the Hopkins-Roy the first time was the top two P4P fighters in hindsight but they were a little green still. What about Roy vs. Toney?

..was in 1993 when Pernell Whitaker (#2) took on Julio Cesar Chavez (#1). If Mayweather vs Pacquiao happens, it'll be the second. It rarely happens coz both fighters must be on same weight class to fight. Even the Chavez vs Whitaker fight was in a catch-weight. Floyd and Pac has been alongside in the list since 2006 and Pac was fighting in 126 lbs. 4 years later this P4P matchup is now on-process. Unbelievable really.

You could make a case that the Hopkins-Roy the first time was the top two P4P fighters in hindsight but they were a little green still. I think you could also make the case that when Leonard, Hearns, Hagler and Duran fought each other at one point the top two P4P fighters in the world faced off

PBF vs Marquez was fairly close to that sort of match up, Former number 1 vs number 2

Yeah, the only other time we came close was Roy vs. Hopkins in 2002, but they couldn't make a deal. I've hated them both for that ever since. If this fight doesn't get made, I don't think I could ever cheer for Pac or Mayweather again.
