Sub-Grappling would be Jacare, Roger, Marcelo Garcia, Xande, Lister, and Arona.

MMA grappling would be Mach Sakurai, BJ Penn, Arona, Lister, both Nogieras, and Busta. Actually there are alot of good judo grapplers entering MMA lately too. Nakumura, Yoshida, etc.

I don't keep up with the judo world, but you could look up the latest Judo world champions, and Olympians.

Also, don't forget Freestyle, and Greco Roman Wresling.
