Carlson Gracie fought in 18 Vale Tudo matches, brought jiu-jitsu to the masses, and innovated many of the MMA training practices we now take for granted. He innovated many seemingly radical ideas at the time, like training without the gi, group classes, and being a well rounded fighter.
These points come from Robert Drysdale's excellent book, The Rise and Evolution of Brazilian Jiu-Jitsu, available on Amazon at https://www.amazon.com/Rise-Evolution-Brazilian-Jiu-Jitsu-Democratization/dp/B0C1JCNQ1P
I'll be talking to Robert Drysdale about Carlson Gracie and this era of jiu-jitsu in the very next episode (#387) of The Strenuous Life Podcast, so don't miss it!!
Cheers,
