Brazilian Jiu-Jitsu has been deemed to be a highly effective fighting art, especially for MMA. But as the sport evolved through the years into an entity of its own, it has also been met by many criticisms.
During his appearance on a recent episode of the JRE MMA Show podcast, retired welterweight fighter and former NCAA Division I and Olympic wrestler Ben Askren pointed out what he felt were inefficient practices employed by Brazilian Jiu-Jitsu schools. He specifically centered on the five-minute sparring rounds during training, and what he felt was the lack of drilling of techniques.
