Former UFC light-heavyweight champion Jon Jones is among the MMA fighters to be classed in 'GOAT' status.
SPORTbible used TierMaker to rank several MMA fighters, both past and present, from 'GOAT' status to 'not a fighter.'
Joining Jones in receiving a nod for the 'GOAT' of MMA is Georges St-Pierre, who reigned over the welterweight division for years.

Below GOAT is the 'legend' tier and features the likes of UFC superstar Conor McGregor, lightweight champion Khabib Nurmagomedov and Anderson Silva.
SPORTbible also created a 'future legend' category and it boasts names like Israel Adesanya, Darren Till and Francis Ngannou.
Controversial as it might seem, a TierMaker wouldn't be complete without a handful of fighters landing in an 'overrated' tier.

Ronda Rousey might be widely regarded as a pioneer for women in combat sports and a UFC Hall of Famer, but brutal back-to-back defeats to Holly Holm and Amanda Nunes has seen her drop into this category.
And no doubt other controversial picks that were placed in the 'overrated' tier included Alistair Overeem, Brock Lesnar and Ben Askren.
