Also - I don’t agree that western African descendants automatically make the best mma fighters. Yes, there were 3 simultaneous African champions but their reigns were relatively short lived when compared to a lot of others. Jon Jones is definitely one of the best of all time, but his career has a ton of asterisks unfortunately. Compare this to the dominance of GSP or Khabib. I don’t think you can really say a single race dominates mma in the way that it does, say basketball or strongman. It’s pretty even in MMA.
