Roger Gracie is known as the GOAT of Jiu-Jitsu, and has been open about his views of people learning Jiu-Jitsu mostly off youtube. For Roger, he learns his new techniques directly from his training partners. He doesn’t watch much Youtube.
He told Graciemag his thoughts (translated from Portuguese)
What is the biggest mistake from a young BJJ practitioner who wants to be a champion?
Copying YouTube positions not training the basics. Maybe it’s the biggest mistake of the kids today, who gets carried away with berimbolo and the like and forgets the rest…
