Based on what you just said why is Chuck a legend? I don't really care if Lyoto goes down in history but who has Chuck beat? Horn lol... Randy who Machida also beat, Tito who he also beat, he lost to Rashad, he lost to Shogun, He lost to Rampage who Machida beat. So he really just beat Monson, Guy Mes, Babalu and a young Belfort who should have been fighting MW and also a young Overeem?
It isn't always about rankings. And how good a guy was. I think we have a different meaning of legend.
The fact that Chuck Liddell basically saved MMA in the U.S. He was easily...easily the most popular fighter in North America. That has a lot to do with his legendary status.
It isn't all about the top guys being legends. People are legendary for different things. Not just being a top fighter.
