[Rocky] In Rocky 3 it's established that Rocky cannot go toe to toe with Clubber Lang, because Clubber is too strong and deadly. But in Rocky 4 he goes toe to toe with Ivan Drago, who's far stronger and deadlier than Clubber. What gives?

Even after Rocky regained the eye of the tiger, Apollo's training program was focused on Rocky *not* standing toe to toe with Lang.

Rocky was in much better shape, stronger than ever against Drago. He also had even more motivation than in his rematch with Lang, cause Drago killed Apollo. At that point, for Rocky it was less about winning the fight cleanly and smartly than hurting the Russian and avenging his friend.
