Fighters who were on their way to winning despite being behind on points

Ali vs. Foreman

I think Ali was ahead in that fight.

Benn v G Man comes to mind, the fact that Nigel was down and out of the ring in the first few seconds, knocked down in the 8th? But still kept coming and slowly eroding the will of his opponent where you knew he was going to win.

Tyson v Holyfield was similar, Mike put a lot of work in the first 5 rounds and after that he was getting a beating.
