Tyson did beat Larry Holmes for Muhammad Ali he said "get him for me" before the bout. How about Klitschko s? They seemed to have each other's backs, maybe someone with more knowledge can provide the info as I haven't followed it too closely... Vinnie Paz "for all the paraplegics if the world or those with broken necks." I'm sure there's more examples... Pacquiao kinda did it for Cotto, mucked up Tony m's eye.
I always feel its overrated. With klitschko's its normal since they are brothers. But Tyson beating up Holmes for Ali is just hollywood style to make it a better story. He was f'ing him up regardless. Ali getting beat up by Holmes was his own fault. Never should have been in the ring. Same with Pac vs Margarito.
Not long after Armstrong was stitched up, and with a huge ice pack to his misshapen face , he looked pleadingly towards his friend, who said " don't worry Henry, I will get him for you " the friend being SRR, the fighter being Zivic, not long after Ray kept his promise. stay safe guys.
