Fighters getting prime beat out of them.

[Larry the boss]

Frazier-Foreman

hatton and forrest not so much imo.

You could definitely make that point with Forrest and Hatton. But for Forrest, I remember being so excited that he had FINALLY taken that next step and then he fought Mayorga and... that was about it. He had a decent career after that but never even came back to the highest level again, not even to lose. And before that, he was clean. He wasn't a great defensive fighter but he didn't really take much punishment and had 30+ fights and we were still wondering if he could actually take a punch. It was downhill after Mayorga for him.

Forrest vs Mosley

Forrest >>

pacquiao / margarito ??

Frazier-Foreman

Frazier was out of his prime already ithink you mean Ali .

[Owlzfan84]

Vazquez/Marquez took all the prime out of each other with their rivalry.

[juggernaut666]

Tyson beating Ruddock did anyone see the unbelievable shots Tyson unleashed on him in 19 rounds total, after the second fight Ruddock looked like he was hit with a bat.

[TOBYLEE1]

Salido/Lopez
Tarver/Jones
Golota/Bowe

Hatton wasn't the same after but not because it was such a bad beating he just couldn't take the loss.

I think it was pigging out on beer and kebabs then losing 50lb in 5/6 weeks before every fight that took Hattons prime away.

Re the thread question, Vernon Paris vs Zab Judah is one example that springs to mind.

Though Paris still quite young and might yet rebound from that beating

[DreamerUSA]

Corrales after the first Castillo fight was never the same and he was only like 27 or 28.
