I hate to say it but Judo wins again in MMA, Karo(Judoka) beat Serra (a world renowned BJJ blackbelt)
Yea Judo is not effective
Where are all the Traditional Jujitsu guys in MMA if it is so much more effective than Judo? The answer is that people who train only kata and cooperatively would get absolutely creamed. While MMA is not necessarily actual combat, it is close enough to show what is effective and what is not.
