When I think Judo fighters in MMA I think of Pawel Nastula, Yoshida, Karo Parisyan, Ronda Rousey. Nastula got thrown to the wolves somewhat in Pride, didn't deliver on a great career in MMA but held his own. Rousey obviously had great success in the women's divisions. Yoshida is a Japanese MMA legend. Karo Parisyan had mixed results at the top level, but I appreciated what he brought to MMA.
