I'm not here to debate the effectiveness of various submission styles. Having spent time doing Judo, Brazilian Jiu-Jitsu, Submission Wrestling, and some limited time in Freestyle and Greco-Roman wrestlings....if it's grappling I am a fan and will spend time learning about it.
From Pankration to Jiu-Jitsu matches to rough and tumble to vale tudo and the like....grapplers have long figured into the toughest man in the room question asked among men the world over.
Whether it's Count Koma traveling the world over, the Catch as Catch Can Carney wrestlers, or Vale Tudo matches in Brazil, the toughest man in the room often knew some grappling in one form or another.
Here's to those that came before whether they wore a Gi, a singlet, shoes, went barefoot, wore a belt, fought at carnivals, on tatame or whatever the case may be.
