many LL practitioners will hang this guy for this article.
but from a grappling point of view, LL its pretty much carlsons gracie jiu jitsu style, im not saying carlos launched anything, im saying their approach to grappling is the same.
they take much pride on leg lock though, and I think back in the days it was a big difference, now days, jiu jtsu guys probably have the best leg lock game in the grappling world.. its just a matter of numbers, there are more jiu jitsu guys training leg locks than any other style of grappling in the world, specially different entries etc.
