12. Larry Holmes vs. Ken Norton
By all rights, Norton wasn’t even the heavyweight champion. The WBC stripped Leon Spinks after he refused to fight Larry Holmes, holding out for a rematch with Ali. That fight eventually happened but it overshadows another classic with one of the best rounds you’ll ever see.

Both men had their moments in this back-and-forth clash. The final round is famous for its craziness. First of all, Norton appeared to be in charge before Holmes came surging back. He was close to finishing the champion but won the decision anyway. A truly epic fight.
