Like many people I got pulled back into UFC because of Conor McGregor. I watched the first UFC fights in the nineties, on VHS tapes rented from my local video store. Ninjitsu vs. wrestling, karate vs. thai boxing, a 150 pound man vs. a 220 pound man — who would win? What style would prevail? It soon became clear that Brazilian jiu-jitsu, specifically the Gracie family brand, was the most effective martial art in the world in terms of one-on-one battles. Any sane man will tap when a choke hold prevents him from breathing, or an arm bar threatens to snap his humerus in half.
