The only reason you would have a guy training 10-14 hours a day, six days a week, would be to keep him chronically exhausted; I've seen Mexican trainers, usually father's, do this if the fighter is running after women. It also helps keep a guy out of trouble if you keep an eye on him all day and put him to bed dead tired.

If that is an accurate depiction of his training, I'm guessing they were trying to keep a potential cash cow out of trouble.
