God Tomasz Adamek is great, 3 titles in 3 weightclasses. And not too many fighters have moved up from Light Heavyweight, and been a successful Heavyweight.

He's P4P top 10 now IMO, i know people say Heavyweight's can't be P4P. But he's moved up from Light Heavyweight so its different, plus Mike Tyson was P4P number 1 at one point.
