Adamek - Walker was pretty damned entertaining as have been quite a few fights in recent times. For championship excitement, Vitali-Sanders was great as was Brewster Lykiavich (sp). The Klits are too dominant unfortunately.
Brewster vs laikovich, vs Wlad 1, not that great except for The ending. Brewster takes a beating and triple left hooks Wlad for a tko. Lewis/Vitali gets my vote though.
Povetkin-Huck was a really good brawl, its up there with Lewis-Vitali & Brewster-Liakovich as the best HW fights of the 21st century. Arreola-Walker was a fun fight too
I think what the threadstarter was talking about is one that would be rated a classic. Not many of those in recent times.
There have been a number of very "good" and entertaining heavyweight fights over the past 15 years. But if we are truly looking for the last "great" meetings, then we may have to go back to the Holyfield - Bowe trilogy.
