I'm still trying to figure why people keep saying that if Wladimir catches him, it's good night. Just because he's big, doesn't mean punches harder than Haye. In fact, despite his size, doesn't Haye punch a lot, lot harder than many other heavyweights?
As St Marco predicts though, I think WK will just jab, jab, grab and wait for Haye to get frustrated and open up. And yes, it'll probably quite tiring having Wladamir leaning on you for hugs all night. Go on Haye
