Guys can only be competitive for so long in the Boxing game. After that, they become like a junkie trying to get that initial high -- its not gonna happen.
RJJ, Holyfield, and others are good examples of guys that should have firstly planned for a rainy day, and secondly should have stopped boxing long ago.
Hatton does not look good and with a long career full of overeating, drinking, drugs etc.... His chances of reclaiming his glory days are slim to none.
Come back for ONE fight against a soft target and then ride off into the sunset for good .... That's the best plan.
