I'd like to see more judo being trained for mma. Alot of the throws don't require a dip down leaving you open. The subs required in sanctioned tournaments need to be applied within a matter of seconds after the takedown. Alot of the no-gi throws are applied from a clinch anyway. This addresses the open shooting problem, the stand-up/rounds issue, and the intial tie-up issues.
I think that judo doesn't get respect as a viable tool from a large percentage of high calibre training talent, which is their right. It might be the time commitment required for sharp techniques or the gi/no-gi issue. (the gi can be worked around for the majority of judo but it's harder than gi training in my opinion)
I'm waiting for the day that a judo master works to adapt the art to an mma variation, a new variation with mma rules as a driving force. No-gi only, takedowns with strike defense, ground position for subs and strikes, and the use of strikes to open new positions would all have to be addressed. Then I believe that there will be a resurgence in takedowns and submissions.
Let's not forget the "WOW" factor of a beautiful judo throw in an mma bout. Stunning. -ken
