3. EliteXC: Heat - The Only Man To Knock Out Big Country
If you're going to be known as something other than the heavyweight champ, be known as the guy who knocked out Roy Nelson - you know, the guy with the granite chin who had never been knocked out before and has never been knocked out since. Junior Dos Santos couldn't do it. Frank Mir couldn't do it. Current title contender Fabricio Werdum couldn't do it, nor could Daniel Cormier in his last heavyweight tilt prior to dropping to light heavyweight. Hell, Stipe Miocic, who went on to defeat Nelson (by decision, of course), flat out stated he didn't expect to knock the guy out - and Miocic hits pretty damn hard. So the fact that Arlovski is, to this day, the only guy who knocked out a dude who generally can't be knocked out short of driving a truck into him - well, that's saying something. Nelson protested the stoppage, but you can judge for yourself.
