Best performance when under pressure

I have to give it to Leonard against Duran in the rematch. What actually happened in that fight as been over exagerated just a bit but considering that Leonard was so good and had just lost his unbeaten record I give him huge props just for winning, never mind the performance.

Azumah Nelson vs Jeff Fenech in the rematch too.

Ok, carrying on with that theme, I'll mention the tragically ending Benn vs McLellan

Lamotta vs Dauthille and Chavez vs Taylor obviously too.
