Retired fighters really should be barred from re-entering the sport. Time and time again comebacks result in little success, other than getting beat up by sub-par fighters and tarnishing their own once great records. Fedor is hardly a stupid man, but just like Mirko Filipovicz at the time he's making a dumb choice now.
Won't watch any of the fights as it'd be heartbreaking to see him get trashed even more.
