Paul is 29 so he relatively young and he hasnt taken a ton of punishment although he does get hit in fights. I dont think he will be a undisputed champ or p4p but may win a title or two and can make a good living. He has a good style and attitude so he will get TV time. His aura of invincibility is gone from others fighters perspectives and even probably in his own mind. Time will tell. Amir Khan seems to be fairing ok after an equally devastating KO so I think he can come back. plus Paul was KO'd by a true top P4P guy with deceptive power. Just ask Kermit cintron who said something like "No one can hit that hard" when Sergio knocked him on his ass and he cried and they ruled a head but.
