The Klitchkos should have nothing to do with Haye after how he slandered them.

Their choice. Would be a fun watch, Haye is dangerous to anyone though, its not a smart move for your legacy. Even though the klitchos are better than Hyae and most likely to win I don't like the risk Haye poses with his skill and punching power he might scab a lucky win and make the klitchkos look bad.
