Apollo's a grown ass man, dawg, word to Cedric the Entertainer. nikka never heeded good counsel. If Rocky had thrown in the towel, Rocky also probably never has the motivation to fight Drago.
Once he recovers from his ass whooping, Apollo's dumbass would probably challenge Drago to a rematch and if permanent damage wasn't done in the first match, it'd sure as hell happen in the second boutIf Apollo was the type to not let ego and stubbornness control him, he never fights Rocky a second time and there's no series
