Joe Smith Jr vs Bernard Hopkins Hopkins didn't want to get back in that ring. Mayweather vs Ortiz Ortiz was conscious the entire time and really just gave up. Berto vs Ortiz 2 Maidana vs Ortiz
Byrd/Klitschko Griffin/Jones But honestly, aside from Leonard/Duran i can think of no other's in major fights thats the opponent quitted just because he was overwhelmed. McCall had mental issues, Golota maby as well Klit has an injury and i tought the judgment and expectation that he should endure where a bit harsh. Griffin was wise a hell, beautifull win lol
Others quit because they are getting beat up or embarrassed. Duran wanted to fight but Leonard wanted to clown. There is no beat down or embarrassment happening.
Margarito / Cotto Made Cotto kneel in submission. Floyd soil his underwear & Oscar withdraw his bravado challenge
All the examples given are verifiable yet they emphasize how different Loma's situation is. Having four fighters quit against him , two of them undefeated champions, is something that may never be duplicated.
