How do you see the above doing against these opponents all at 205. Presume we have USADA testing in place. Ken Shamrock Tito Ortiz Vitor Belfort Wanderlei Rampage Liddell Evans Machida Rua Jones
Gus beated Jones - when? I know they fought once with much moaning and bitching over the result, but it was the right winner. A close fight with Jones winning three rounds. The vagina you're talking about. You mean when he got hit with a huge punch by Rumble and never recovered? That's part of the game.
Ortiz, Page, Liddell, Evans and Rua have never been connected to PEDs so it's a bit disrespectful to lump them in with the other known cheaters.
I've "lumped them in" with guys who probably make up the best ten LHW fighters ever. If you think they don't belong on that list that's upto you, I personally think they're good enough to be there.
It's not about who I rate as the best, the USADA caveat in your OP implies that you assume every guy on the list was on something. Maybe the aforementioned were using PEDS and maybe they weren't but there's zero proof either way.
It implies that we can assume everyone is USADA tested, including Gus and Rumble. It's just a list of the best LHW fighters throughout history.
