You may be surprised to find that not all black belts are great human beings. You will also find that today's guest is both a black belt and a great human being. Mike Mahaffey( @OldBastardBJJ ) has made a name for himself by helping other "old bastard" grapplers stay on the mat consistently. Enjoy this wide-ranging conversation where we talk jiu-jitsu politics, martial arts, and where we brutally insult some random blue belt named Zac.
