WWE has a video looking at the Top 10 WWE Submission Superstars of all time at www.youtube.com/watch?v=YKO5CRJ7ISE.
The list is:
10. Tazz
9. William Regal
8. Sgt. Slaughter
7. Daniel Bryan
6. Dean Malenko
5. Chris Jericho
4. Ric Flair
3. Bob Backlund
2. Kurt Angle
1. Bret Hart
Interesting was Bret Hart putting over Ric Flair (given what they have said about each other publicly in recent years) while Daniel Bryan buried Flair's use of the Figure Four saying he didn't win a lot of matches with the move and wouldn't have rated it near the top.
