In what fight did a fighter show most heart/gameness? regardless of whether they beat the odds and came back to win.
Thrilla In Manila. Both fighters showed tremendous courage and heart, they literally had nothing left at the end of the bout, Epic stuff.
Kessler vs Froch. Showed that he(Kessler) could beat one of the toughest boxers in the sport in a brawl.
JMM is the sixth round vs Pacquiao. Hurt, bleeding, yet still willing to stay in there and take a big risk by allowing Pac to get close enough so that right hand could be landed.
Roberto Duran vs Sugar Ray Leonard 2 lol On a serious note: Thrilla in Manilla Khan vs Maidana and Garcia
Amount of blood AA was choking down was insane.... but he was still fighting his heart out and actually pushed forward and wobbled Miranda a bunch of times.
