Pavlik has money but he will probably gamble it or drink it away. The guy doesn't seem like the type who is good with finances, and he is a pretty bitter guy seems like the type who will dwell a lot and look back.
It's weird that he would retire before a fight that would give him another good payday and possibly revive his career, if he lost to Ward he probably thought it would hurt his legacy more, I don't think he retire for health concerns, I mean the guy is a drunk or used to be a drunk that would effect his liver, kidneys and long term health too. I think he copped out, probably felt he couldn't beat Ward so he retired.
I think he will comeback once he needs the money again, but you can live pretty well in Youngstown with 2 million in the bank.
