royce gracieThere was really only one true competitor to Royce Gracie and his Brazilian Jiu Jitsu style of fighting during that initial UFC tournament way back in 1993, and that person was a shoot fighter or shoot wrestler by the name of Ken Shamrock. Shamrock would eventually become the first Pancrase organization champion, immediately making him a part of shootfighting history. Though he fell quickly to his Brazilian Jiu Jitsu counterpart at UFC 1 and in the process lost a key style vs. style match up, his ability to submit kickboxer Patrick Smith with a heel hook solidified shootfighting as a martial arts style worth studying.
