I composed the below post for a thread in the HW forum, but I thought it would be a good cross-post to threadstart the issue for the Grappling forum. HW: Fabricio Werdum LHW: Antonio Rogerio Nogueira MW: Ronaldo "Jacare" Souza and Demian Maia WW: Andre Galvao and Nick Diaz LW: BJ Penn and Shinya Aoki For those of you new to MMA and grappling: the ADCC is the Olympics of Submission Wrestling. It happens once every two years (although it was annual when it first started; there have been a total of 8 competitions thus far: 1998, 1999, 2000, 2001, 2003, 2005, 2007, 2009). Fabricio Werdum is the ADCC's greatest HW ever with two 1st place finishes, one 2nd, one 3rd, and also a 3rd place finish in the 2003 Absolute tournament. Although Jeff Monson has two 1st's, two 2nd's, and one 3rd, he achieved his best finishes in the ADCC's early years: when the competitions were held annually and when competition wasn't as stiff as it is today (it should still be noted that Monson continues to medal to this day, incredibly). Furthermore, Werdum's two 1st place finishes were from 2009 and 2007, so he can easily be called the world's greatest active HW grappler. The other notable is Marcio "Pe De Pano" Cruz. The greatest LHW ADCC grappler of all time is "Xande" Ribeiro; Roger Gracie and Alexandre Ferreira are the other greats from the ADCC, and Roger is probably known as the most accomplished overall of these three; nevertheless, he only dabbles in MMA. The most prominent ADCC competitors who have also competed routinely in MMA are Ricardo Arona and Ricardo Almeida. Arona won the LHW competition twice (in 2001 and 2000), and also won the Absolute Tournament 2001. Almeida finished 4th in the Absolute and 2nd in the LHW in 2001, 3rd in the Absolute in 2000, and 3rd in the LHW in 1999. The only problem here is that Almeida moved down in weight over the course of his MMA career eventually landing in the WW division, and Arona was never really known for a strong guard, but more for being a BJJ black belt who fought like an Olympic wrestler (he also hasn't competed at an elite level in MMA for quite some time). Shogun has only one submission in his career, so to put him at #1 would be ridiculous. So I think the best, currently, are either Antonio Rogerio Nogueira or Gerard Mousasi. Since Nogueira has fought the more elite competition, I'm going with him. The greatest MW ADCC grappler of all time is Saulo Ribeiro, and the current champion is Braulo Estima; however, the greatest grapplers in this division to have competed seriously in MMA are Ronaldo "Jacare" Souza and Demian Maia. Souza was the runner-up in the Absolute Tournament 2005, the champion of of the MW division in that year, and the runner-up in the MW division in 2003. Maia was the champion MW in 2007, and runner-up in 2005. The greatest WW ADCC grappler of all time is Marcelo Garcia; the other standouts are Pablo Popovitch and Jean Jacques Machado. Andre Galvao is obviously known as the greatest Jujitsero that has competed in MMA at WW (he took 2nd in the MW division at this year's ADCC, but the bulk of his resume lies in traditional BJJ competitions); however, since Galvao has only 6 MMA fights to his credit, I think I'll also pick a more accomplished MMA fighter. Of the elite WW's in MMA, I'd say Nick Diaz has the best guard. The greatest LW ADCC grapplers of all time are Royler Gracie and Leo Vieira. The best in MMA is Shinya Aoki (he just beat Shaolin, and he has a higher submission percentage, so I don't understand why everyone is putting Shaolin). I was tempted to omit BJ Penn after witnessing his guard get mutilated by Frankie Edgar, but then I realized Edgar would do the same thing to Aoki. Penn's guard is unbelievable; of course he's at the top. Alright, sound off. What are your lists?
