Or the likes of Chris Arreola could one day wake up and realise that they should actually try and get into some sort of fighting condition.

There isn't really a heavyweight out there who is conditioned enough to be able to use the full size of the ring at a good constant pace for anywhere near 12 rounds. Maybe David Haye is an exception, as he did this against Valuev, but he didn't throw many punches.

Guys can make a good enough living by beating up other out of shape guys, and then losing a title shot against a Klitschko, before beating another bum and completing the full cycle again.
