The things for Haye is that he didn't have much choice but to fight the never-has-been, Audley Harrrison. The Klitchkos won't play because he refused to sign one of their ridiculous deals that means you are tied up to fighting them and them only for about 3 years. He would give either a good fight and might even beat either or both, but it's not that they worried, it's just that they have the whole thing sewn up and they can fight or not at their leisure. It's all about business. The heavyweight level of boxing is a farce right now.
And in the meantime, Manny Pacquiao just won a title at this eighth different weight, badly duffing up a serious fighter far bigger than him... and at the same time as being an MP is the Philippines... now that's some achievement. Almost as unlikely as an ageing architect getting one over on a group of youths in a street fight...
