Greg Jackson has accomplished the rare feat of making himself an MMA celebrity without ever stripping down and setting foot into the Octagon. He has become a star trainer, and not without a whole host of good reasons. For one, Jackson has been teaching mixed martial arts since 2000 at this point. He has played a crucial role in the careers of many champions and all-time greats, including Georges St-Pierre, Jon Jones, Carlos Condit, Donald Cerrone, and more.
Throughout all of this, Jackson has garnered a reputation as one of the best strategists in the sport. They've called him a sport-killer and a hero, but no one can deny that Greg Jackson knows how to come up with a gameplan.
