i don't think so personally, he's the richest boxer alive, it's quite safe to say he's not in it for the money, and it's not like after he retires he'll be poor as he has golden boy promotions, he simply loves the sport, he should realise that he's past it, but sometimes the heart wants to carry on, it happens to many a sportsman
Oscar doesn't really need cash with all the promotion he does on the side. I think he's running into what all old fighters run into, he doesn't want to admit he's finished.
