Don Frye, Yoshida, Fedor (the current #1 fighter in Pride) Newton, Trigg, Takase (who just subed a top Anderson Silva), Herring (he Remco his grappling coach is a judoka), etc. Almost all the Japanese fighters have done judo. It's a good base for grappling. Christophe Leninger was not an olympic level judoka but a national judo champ. In UFC 13 Guy Mezger said he was one of the hardest guys he ever fought. Not to mention he was in his late 30's.... Judo (IMO) is better for the street (wrestling as well) because it forces you to be aggressive and stay on up on top/on your feet. Sho-judo
