In MMA we generally have the big four MA's that every fighter must know: Boxing, Muay Thai, Wrestling and Brazilian Jiu Jitsu. However, I think that there are aspects of other TMA's that are underestimated in their use in the octagon. For example, many kicking techniques in karate and TKD are underutilized IMO. Also many grappling arts from around the world get lumped in with wrestling whereas wrestling is just an umbrella term for a wide variety of arts, ie: Sambo, Judo and many regional styles. I guess in the evolution of MMA as a sport the most effective techniques were the ones that prevailed. I am not nostalgic about the early days of MMA where it was about style vs style. On the other hand, I'm wondering if MMA as a sport has pigeon holed a certain skill set and this prevents fighters from exploring other techniques that, when combined effectively, can be devastating and entertaining. Your thoughts?
