As far as being ranked, the guy is just about top 10 arguably, he doesn't have too many good wins in MMA.
But as far as being the best heavyweight, he's Top 5 alongside, Fedor, Barnett, Arlovski and Cain IMO. I know Cain is green, but there isn't a guy he wouldn't take down. And his top game seems brilliant, so I think he'd beat most people.
Fedor fights I want to see..
Fedor vs. Josh Barnett
Fedor vs. Randy Couture
Fedor vs. Tim Sylvia -
Fedor vs. Andrei Arlovski -
hmmmmm, i wonder how many become reality..
