Trying to remember all the guys who actually quit. I'm sure there are plenty, but my memory ain't as good as it used to be. LOL!
Gotta go with Cotto vs Margarito: Cotto knew something was up. He was boxing Margarito's ears off and touching him up. Then all halfway thru the fight, Margarito starts killing him. Cotto's face told the tale. When he took the knee, he was like WTF!!! Then later come to find out Margarito was cheating and who knows how long he and his team had been doing that to their wraps. F' Margarito!!!
Honorable Mention: De La Hoya vs Pacquiao. Oscar was weight drained and past his prime. Manny was lumping him up. Too fast, crazy angles and Oscar wanted no more of that, so he quit on his stool. Oscar should have never accepted that fight, but it helped cement Manny as a SUPERSTAR. So that, I guess, is a good quit.
As much as I love Rigo, he was getting embarrassed by Loma. He called out Loma and was talking mad trash on social media. Come fight night, he was a no-show, then blamed it on a BS hand issue or something like that. I know the 2 weight class jump was difficult, but DAMN man. He gets no pass from me.
Same with Nicholas "Axe-man" Walters. Loma embarrassed him and he quit on his stool. Don't think Walters has fought since. He also doesn't get a pass from me.
My favorite funny moment back in the day was Oliver McCall crying in the ring in the Lennox Lewis rematch. That was just crazy!!! But knowing what we know today about mental health, it's not so funny.
