This week we're joined by Robert Drysdale!  Robert brings his extensive experience, both as an elite grappler and historian, to discuss the BJJ "generation gap" and how he's witnessed the art evolve.  A really insightful conversation about the importance of history, the evolution of coaching, how rulesets have changed the sport, and fundamentals vs. trends.Opening Closed Guard - the book & film:https://www.closedguardfilm.com/Robert's Instagram:https://www.instagram.com/robertdrysdalejj/Coolness versus Efficiency: The Crisis in Jiu-Jitsu, by Robert Drysdale:https://bit.ly/3NUXTtYHow to Win at Jiu-Jitsu while Keeping it Real, by Robert Drysdale:https://bit.ly/3aZytgcMental models discussed in this episode:Curse of Knowledgehttps://bjjmentalmodels.com/curse-of-knowledge/Extreme Ownershiphttps://bjjmentalmodels.com/extreme-ownership/Path of Least Resistancehttps://bjjmentalmodels.com/path-of-least-resistance/Static vs. Dynamic Controlhttps://bjjmentalmodels.com/static-vs-dynamic-control/Win Conditionshttps://bjjmentalmodels.com/win-conditions/Economy of Motionhttps://bjjmentalmodels.com/economy-of-motion/Cognitive Loadhttps://bjjmentalmodels.com/cognitive-load/Do What Workshttps://bjjmentalmodels.com/do-what-works/Concepts Over Techniqueshttps://bjjmentalmodels.com/concepts-over-techniques/Short-term/Long-term Paradoxhttps://bjjmentalmodels.com/short-term-long-term-paradox/Don't forget to check out BJJ Mental Models Premium!If you love the podcast, you’ll definitely love our premium membership offerings.
