"All the greats, you look at Marcelo, Roger, Braulo, those are guys who are considered the best of all time and they all go out to finish people."

Haters, brawls, dirty moves, drugs and rivalries, these polarizing competitors always get caught up in the mix.

Though perhaps not as exotic or fear-inspiring as the dreaded heel hook, the kneebar is one of the most versatile leglocks in jiu-jitsu. It’s a submission that can be finished from top while passing, set up from a variety of different guards, and it's legal in the gi.  

With every major title you acquire in this sport comes more and more responsibility to the community that has contributed to your success.

Few matches have captivated the jiu-jitsu world quite like the 2017 rematch between Roger Gracie and Marcus 'Buchecha' Almeida.
