I have watched the AJ vs Povetkin match over and over. As I stated earlier, Povetkin definitely outboxed AJ in that match. Povetkin is known for learning from his mistakes, renewing himself, and becoming a better boxer in his upcoming fights. I don't see anyone other than AJ that has a chance to defeat Povetkin in the heavyweight division. I think he will beat Whyte, Ortiz, Bellew, Hughie Fury and Parker easily to get another shot for these 4 titles. And when he does, I think we will see a different Povetkin, he will be named "Giant Killer" in my opinion.
Before Pov retires, I'd like to see him get Jarrell Miller into the ring. I'm curious about that one (even though it might never happen).
No chance. His only option would be to go for a number 1 mandatory position, but Wilder has run from Povetkin his whole career, so good luck that happening with the WBC, and the WBA, IBF and WBO aren't going to give him another crack for that spot anytime soon with many in line already. Povetkin's best route would be fights with Whyte and/or Miller. And if he gets back in the win column and generates some interest in the UK, he could be a late replacement fighter if say Fury pulled out for Joshua vs Povetkin 2. But that's still a huge if.
