Fights That Ended Careers

[Dr Rumack]

Cotto was never the same after Marg pummeled him...

Following that fight he got a gift decision over Clottey, then he got beaten up even worse by Pacquiao. Then he had 3 straight wins over low level competition to build him up as a PPV attraction again and then he came down to earth against Floyd.

Cotto fought well against Mayweather though. Margarito took his prime but he didn't finish him.

Marquez - Diaz I Diaz got his career ended in the first fight

That's a good one. JMM ruined him.

I'll never get over how badly the HBO crew misread that fight that night, with the exception of Kellerman who was the only one them who could see what was really happening.

Felix Trinidad ruined Vargas, Mayorga, and Reid's careers.

Indeed. Vargas lost most of his of punch resistance and a significant amount of his balance following Trinidad. Literally brain damaged.

gatti vs ward 1 was the end of both fighters....

Willard v. Dempsey (Literally for Jess)
Marvis Frazier v. Mike Tyson (19 seconds!?)
Roy Jones v. Antonio Tarver (not ruined, but his P4P brag was pretty much done)
Ali v. Foreman (Foreman's mind went into a strange place after this)
