This is the "other four kings" thread So we have Benitez-Duran-Leonard-Hearns Sanchez-Nelson-Gomez-Laporte Arguello-Chacon-Limon-Boza Edwards Chavez-Camacho-Rosario-Ramirez Louis-Walcott-Marciano-Charles Who else??
I guess I didnt clarify, it has to be four boxers who fought each other, all four fighting the other three. I dont think Marquez fought Morales, IIRC
I think you killed your own thread then with the OP honestly. Im not sure there has been another set of 4 great fighters in the same weight class who have all fought eachother at least once.
I will say, to poke a bit of fun at this topic, that there are many 4 kings in Bolivia probably...have you seen Saul Farah's record on boxrec ? they stopped counting because boxrec doesnt recognize fights in Bolivia anymore, but he fought many guys with records like 10-60 over the course of his career, and those guys fought between them too! LOL, he has defended the Bolivian national Heavyweight title like 30 times but many of those defenses came against guys with 0-8, 1-15, 2-25 records lol...and there is a number of boxers against whom he defended 5 times each, and as I said they all have fought each other too! Huge joke Bolivian boxing is!
