[Halfway]

Royce Gracie - He really is the father of MMA in the US, he introduced the sport and BJJ, something no one knew about and they quickly saw how it was dominant against most popular MA's. Really showed that the smaller man can have the advantage in a fight.

Frank Shamrock - He was the first prototypical MMA fighter. He was a great grappler and had a solid striking game (not great) and he fought with ferocity like no other.

Randy Couture - Great ambassador to the sport. Very respectable and the epitome of an underdog. I believe he was the first to hold two different belts in two different weight classes. Tons of heart and he seemed to shine as he got older.

Kazushi Sakuraba - Sort of put an end to the Gracie legacy. Showed that BJJ wasn't the only grappling style that could work in MMA. He was inventive, never had a bad fight and showed tons of heart, arguably more heart than any other fighter.

BJ Penn - Came out of nowhere and shocked the world. A natural LW who has not only fought at 170 but was champ, beating the most dominant WW, fought at MW & HW. He took the road less traveled and did it as a 155er which should never be downplayed.
