I think some distinctions are required due to timelines and natural weights. P4P Prime Duran Leonard Hagler Hearns H2H Leonard Hagler Hearns Duran I think Prime Hagler would beat Leonard who does have wins over the other three although a few of them have an asterix for me.
In my mind Hagler is physically smaller than Leonard and Hearns so with that said; Duran Hagler Leonard Hearns
They were legends and amongst the best there have ever been. 70’s Duran is arguably the greatest fighter in history and rivals Ali, Sugar Ray Robinson, Charley Burley and perhaps Floyd Mayweather for that accolade. Sugar Ray Leonard may be the best ever at Welterweight and rivals Sugar Ray Robinson. Some think he was the best ever at his peak a mean SOB. Marvelous Marvin Hagler what a man what a warrior a consummate profession probably the best ever Middleweight in history. If you could devise what a boxing champion should look like you would come up with Marvelous Marvin.Thomas Hearns “Thommy” is the most exciting fighter I have ever seen virtually unbeatable at Welterweight and Junior Middleweight, Leonard did it but paid a heavy price in the process in fact anyone who beat Thommy paid a price. He outpunched fighters and outboxed boxers. He literally could beat anybody.
I would ask what the analog for Hagler would be to Duran fighting Hagler and...I mean...theoretically...
Pound 4 Pound Duran Leonard Hagler Hearns What a great group. I am of the opinion that if Hearns had a Muhammad Ali type chin he may have become the best fighter of all time.
