...Gracie Jiu-Jitsu is more effective than the typical sport/tournament style BJJ that is commonly taught? How else can you explain why he is so successful in implementing his submissions against BJJ black-belt level opponents? I don't even think Demian Maia or Jacare (who are two of the most accomplished BJJ competitors in MMA) have submitted black-belt level opponents as consistently as Ortega (in MMA). What gives?
I know the Gracie bros. can sometimes come off like snake oil salesman, always selling their style of "Street" BJJ vs Sport BJJ, but I'm starting to think they may be right. Thoughts?
