What happens to Haye if he actually wins a world title and somehow negotiates past the Klitschkos contract? I can't see any of the organisations liking a champion who wants to defend their belt once a year.
If Haye isn't getting extra food and gym time off camera, then he'll be ratty as ****. Also, he won't have Adam Booth to stroke his shoulders, gaze into his eyes, and gently talk him through his more stressful moments. Unless he's there off camera too. Remember, this program has nothing to do with sacrifices, challenges and hardships. It's just an outdoor version of Celebrity Big Brother.
Or get Chisora to creep up to Haye at night when he's asleep with Chisora whispering into his ear.... "You glassed me...."
Come off it C-Pole - they have to dodge the Spiders and Snakes and Lizards and have a bowl of rice a day to survive.
