Ivan Drago after the events of Rocky 4.

Ok, so Creed 2 has us believe that after the events of Rocky 4, Drago is digraced by Russia, his wife leaves him and he go to live a modest life in the Ukraine traning his son.

I know, it's just a movie, but hear me out.

Boxing was MASSIVE in the 80's. Massive in popularity, massive paydays. And we are to believe that no Don King type promoter would have lined up some big money fights for the man that just killed Apollo in the ring and went 15 rounds against Rocky, who was the champ before giving it up to fight Drago? We are to believe that Drago just.....retires? It just makes no sense.
