Brehs gotta apply some logic to this. Honestly, what MMA has proven over the past 20 years, is that the most dominant martial arts are Muay Thai, Amateur Wrestling, BJJ, and boxing. How many other stand-up martial arts have been COMPLETELY exposed in the format? Kempo, Karate, Savate, Capo, Tae-Kwon-Do, so much of that shyt has been rendered kinda impractical. Machida is making karate work but he and who else? It's the principles of the four that I named that basically every truly dominant MMA fighter has used.
With that in mind? Zangrief, Hugo, King, and Sagat would be competing at the pinnacle of the game.
And low key?
