In today's sport, everyone is mixed martial arts now obviously. There is no fighter that is Just a boxer, or just a wrestler, or just a grappler etc. But there are some fighters that while they have a mixed arsenal, they stick primarily to their strongest discipline (eg. Ben Askren is a wrestler through and through, Shinya Aoki is a grappler etc.). So when you think about those fighters whom are mostly purists to their strongest discipline, it got me wondering, who was the last purist grappler to hold a UFC belt....actually....have any?
