This is where most of my own concern tends to come in.

Any when I mean better Judoka, I don't mean better competitors but better all around practitioners, both in the narrow sense and maybe even the full sense that Kano was seeking.
*Great details on how this happened in the "Vote for Yosh" episode of the Judo Podcast for those interested.
