1. Jim Miller
A Cage Fury Fighting Championships titleholder before he made his move to the UFC, Miller has earned the respect and the admiration of the masses. Rarely in a dull fight, the New Jersey-based Brazilian jiu-jitsu black belt has been a key figure in the lightweight division since 2008. Much of his sustained success can be attributed to nails-tough durability, a no-nonsense approach to his craft and rock-solid grappling chops. Miller has launched a record 39 submission attempts at his 26 UFC opponents, choking Yancy Medeiros unconscious and coaxing tapouts from David Baron, Duane Ludwig, Charles Oliveira, Melvin Guillard and Fabricio Camoes.
