Fighters with the best recuperative powers in boxing history?

IMO (just my sometimes weak opinion) Hearns knew he couldn't do anything else but come out winging! He was bad a r s e and showed it early but this was, yet, another fighter bringing his punching power UP into a heavier division and that doesn't always bode well as the rounds tick off and Marvin's certainly not going anywhere against anyone. I may go and watch it on youtube again right now.
