I think we need to chill out with the "Cain is done" and "Cain needs to retire" talk. If Cain was in any other division other than Heavyweight I would probably agree that his career is over. But the heavyweight division is an oldman's playground. All the relevant fighters are over 35 years old. Not to mention you have washed up fighters like Roy Nelson, Mark Hunt, Arlovski etc. still remaining relevant. If you were looking for a division which could be kind to an old broken body like Cain's then you couldn't pick a better one than Heavyweight. Cain will be fine. He just needs to adjust and realize he's to old and fragile to train the way he did when he was younger and healthier.
