(1) Akira Shoji (Black belt in judo but no title in judo) knocked out Wallid Ismael (8 times BJJ champion who has defeated Renzo Gracie, Ralph Gracie, and Royce Gracie) in R2 in Pride 4.
(2) Igor Zinoviev (Black belt but only a local (NY and NJ) title in judo) defeated Mario Sperry (3 times world champion in Brazilian Jiu Jitsu). He knocked out Enson Inoue in 44 seconds in 1996 Vale Tudo Japan.
(3) Don Frye (2nd degree black belt in judo) defeated Amaury Bitetti (1995 world champion in Brazilian Jiu Jitsu) by TKO in UFC8. Don Frye spent a lot of time practicing judo before the bout with Amaury Bitetti. Frye knew that by practicing authentic judo, he would be completely prepared to take on the BJJ world champion Amaury Bitetti. That is why Frye looked so confident before the match, and he proved himself as we all know. After Don Frye won the Ultimate Ultimate 1996, Jeff Blatnick said to Frye that " Your submission skills have greatly improved." Frye then said, "I spent a lot of time practicing judo." These top BJJ fighters were unable to submit these totally unknown judoka who had no title in judo and lost the bouts in NHB. If BJJ is so much better than judo, then why did these top names in BJJ failed to apply any submission hold on the ground? The fact is that top BJJ fighters were defeated in NHB matches by no name judoka means that it is not very difficult for highly trained judoka to defend themselves against submission holds. Learn true judo, then you will learn to beat BJJ black belts on the ground.
(4) Yasuichi Ono choked out Jorge Gracie (Helio Gracie's older brother) circa 1950. These are four cases in which no name judoka defeated top BJJ fighters.
(5) Masahiko Kimura (7th dan BB undefeated for 13 years in judo) defeated Helio Gracie (the self-proclaimed founder of Gracie Jiu Jitsu) by breaking two bones in the left arm of Helio, by udegarami. Helio Gracie was hospitalized for multiple fractures. In this bout, Helio was unable to score any counter or reverse. Kimura defeated Helio on the ground using a ground technique which is supposed to be BJJ's strength.
(6) In 1974, Wilhelm Ruska (1972 Olympics judo gold medalist in over 95kg class and absolute division) destroyed Iwan Gomes (then the no. 1 man in BJJ) by punches on the ground in a vale tudo match. (5) and (6) are records of what happened when top BJJ men fought top judoka. In both of these cases, these BJJ men were brave enough to challenge top judoka. But the bouts ended in executions by judoka
