Dudes need to chill out and listen to the interview. What the thread starter posted was correct, Rener said that Eddie Bravo's Jiu Jitsu 'filter' was designed to work best for guys just like him - flexible (he never said it won't work if you're not flexible, just that it works BEST if you're flexible).
He ALSO said that Helio's Jiu Jitsu was filtered (there's that touchy word again) to work best for for people like him - the smaller, weaker person. Also mentioned was that if an MMA fighter taught Jiu Jitsu, it would likely be filtered to work best for strong, atheletic types (probably was referring more to Frank Mir than Shinya Aioki).
The basic premise being - everyone teaches Jiu Jitsu through their own filters. They'll teach what works best for them. Which honestly, makes a whole lot of sense, and is true for any good martial arts instructor.
(Note: If a martial arts instructor only teaches you stuff he doesn't personally use, and refuses to teach you what works best for him - it's time to find another school).
As always, lots of respect from Rener. He's a red belt-level salesman for sure, but never one to talk down on others.
(He also gives props to Eddie in the interview, calling him a "Jiu Jitsu scientist")
Cheers
