For my money ADCC has always been the greatest grappling tournament. It brings together great athletes not simply from Jiu-jitsu, but judo, wrestling, sambo and MMA as well. The clash of styles makes for incredibly unique matches and outcomes. I also love the emphasis on takedowns. While many BJJers bemoan the guard jumping penalty I applaud it as the tournament’s greatest strength. Grapplers cannot be one dimensional; they must understand how to dominate the match from the feet to the floor. I also love the international feel. Qualifiers are held from around the world, it’s the closest our sport may ever get to an Olympics.
