For most, I'm sure it was the Royce Gracie influence but I coulnd't relate with him at all. Royce was a pure jiu jitsu guy and I have been a striker since I was a kid. For me it was when I first saw Nog vs Coleman. Nog was outstriking Coleman on the feet and totally dominated him on the ground. Nogueira had the best of both worlds and it really opened up my eyes. The triangle armbar combination was beautiful. I fell in love with submission grappling ever since and have never looked back. Striking almost seems like an ex girlfriend now.
