People who do 'traditional' bjj don't focus enough on standing techniques.
Saulo Ribeiro and 'Margarida' Pontes seem to have game when it comes to takedowns. Just because their Bjj, don't assume they can't throw.
BJJ is great at what it specializes in (ne waza), but it alone isn't "combat effective"
If Bjj is all a person knows, then it is not combat effective. If Pedro Sauer doesn't teach anything other than tournament Bjj, then it will not be combat effective. He has an affiliate school in our area, and so, I know they understand the basics of Gracie Jiu-jitsu (just check Sauer's resume).
I understand what Shogun is saying when he says that they do not sprawl, but pull guard. This is not wholly true, we have all seen Bjj guys sprawl (if not, then get a hold of Marc Laimon's Tournament Tested Techniques
A friend of mine put a front-headlock (free-style variation) on a black belt in Bjj, and the guy could not escape it the entire match. I am not saying Bjj doesn't have problems. I am saying that Gracie Jiu-jitsu is combat effective.
