Most gained, most lost, in one fight.

[ICB]

Douglas vs Tyson
JCC vs Meldrick Taylor 1
Lewis vs Ruddock
Jones vs Tarver 2
Curry vs Honeyghan

I'll think of some more later.

Must admit I disagree with most of these choices. Douglas gained nothing from the Tyson win, he surrended his titles in his first defense, balloned up to over 20 stone and disappeared back into obscurity. Tyson on the otherhand remained the most talked about, controverisal and feared boxer for the next decade.

Tarver gained very little respect from the Jones wins most people still can't stand him and few rate him as a great so he didn't gain a whole lot, although Jones clearly lost his invincible aura after that fight.

Definitely Barrera Hamed is the best example, others I can think of are Liston Ali both fights, Ali became a legend overnight, Liston faded into obscurity. Another would be Duran against DavyMoore, Duran rebuilt his career that had looked as good as over, champion Moore never won a big fight again and died not long after.

Bilbo i think you misunderstood the topic was who gained most and lost the most in one single fight not what they done after but from one single fight Douglas was first man to beat so called baddest man on the planet and Tyson was never the same and lost his aura of invincibility.
