I would say yes. Let's take look at the illustruous career of this legend. Firstly he has defeated Serra and Chonan, two fighters who destroyed GSP and Anderson Silva respectively. Secondly, pre-Serra GSP, the killer who was head-kicking and armbaring the likes of Matt Hughes, could only manage a measily decision against Karo. Thirdly, while everyone talks about Ronda's judo, let's take a moment to remember Karo's judo. He ragdolled Nick Diaz and essentially got him kicked out of the UFC, the same Nick Diaz that KO'd the current WW champ and arguably defeated GSP and Silva. I will not delve into plethora of other reasons (including: WEC champion; destruction of the Dong; and knocking Phil Boroni into retirement), but evidence suggests Karo is the elite of the elite and HOF worthy. Thoughts?
