UFC commentator Joe Rogan admitted that he considers the former dominant champion of the promotion in the flyweight Demetrisus Johnson the greatest fighter in history.
“It's hard to say, but it's probably Mighty Mouse. At his peak, he was incredible, very fast and did things that were unbelievable. He threw Ray Borg with a suplex and caught him on the armbar while he was falling down.
In his prime, he fought world-class opponents and they couldn't even hit him. He worked at angles they weren't expecting, tricking and throwing techdowns, throwing high kicks when they thought he would translate. He destroyed them with some special magic,” Rogan said on the Hotboxin’ podcast.
