The tapout is what separates MMA from almost any other major fighting sport. Fighters of ground fighting backgrounds use principles of leverage and simple physics to put opponents in inescapable positions.
Watching the technical displays on the ground is what brought me into MMA and I would like to take a look at who is the best at making the other guy tap.
This list is a look at the best ten submission fighters currently in MMA, not of all time, so no Royce Gracie on this list.
My criteria was a mix of percentage of wins by submission, number of submission wins, previous exploits in a submission art (such as a Jiu Jitsu World Championship) and impressive submission victories.
