I think if Haye did stop Wlad in the early rounds, rather than it being a 'is that all there was' it would be like a HW Pacquiao-Hatton with people exhilirated.

In terms of interest for the HW division, it would be far better for an exciting Haye win than any win by Wlad. Haye is divisive, but the Klitschkos for all their talents don't really divide opinion. There's a small pocket who either love or hate them (Lyle & Hornfinger respectively) and everyone else is kind of 'meh...'
