Most heroic in defeat

[Hulk]

I saw an article related to your thread today. Corralles VS Mayweather, Corralles was getting demolished, getting knocked down 5 times. Each time he got up and kept trying, it took for his corner to step in to end the fight and he was very upset about that.

That was pretty damn heroic.

Excellent example. I'd also say that Corrales against Clottey was heroic as well, Diego was outweighed and outmatched late in his career at 147 that night. He kept getting up and trying to KO Clottey.
