He can still fight but having that thought of doing other priorities will make him less than with the best that he can. Manny can still make a lot of money with his fame and body through his age but I agree just for these showmatches and not with pro anymore.
And what if the crazy mind of the Paul brothers would come to that point that any of them would invite Manny to a showmatch and sure, it will make him a lot of money to be honest. More than probably the usual amount he's getting from his pro matches.
And so if he wanted to make a comeback in pro boxing (not exhibition), Manny should shelve off everything in the table and focus on the fight at hand. But I guess still up to him if he wishes to make a comeback or not. Maybe his family doesn't want him to do so because he is not that young anymore. He can do exhibition just to keep him in fighting, at least he won't get the damage as severe as if he make a pro fight comeback.
I think if it's going to be about the focus, that's where the problem starts. He can multi task and he believes on that while being a public official and a boxer, a pastor and now with other businesses that he's partnered with.
I've heard that his wife is already set for good and she doesn't want Manny to get back in boxing because they're already rich and can live the rest of their lives into so many generations for their kids without having problem.
