I should elaborate.

Firstly what you said used to have merit, pressure fighters with chin and pop like Sanders, Brewster, Peter and Povetkin and if he ever fought him Chisora who try to bull their way inside and land money shots on Wladimir used to have the blue print. But modern Wladimir is far too defensive to ever succumb to such methods, he will just tie them up hug and lean his massive frame on them, tire them out. He learned his lessons since Sanders and Peter. This type of opponent will never trouble Wlad again.

Haye is different than the other guys like Thompson and Chagaev, Ibragimov and Chambers.

Haye is faster, has decent range, likes to hang on the outside and dart in for quick explosive attacks and get the hell out relatively unharmed. He can do this with Wladimir and survive all fight if he is very focussed asnd sharp and because he hits hard enough to deck Wladimir he only has to land the lottery ticket once to have Wlad in trouble.

I would like to see Wlad/Haye 2 with Haye's toe being in good repair haha. Seriously though I think he could do better. Even a 30% chance is better than Povetkin with no chance!
