Shamrock? He fuckn sucks If you think he is any good you dont know shit.
You must be like 12 to think that. He is a true legend, and a pioneer of MMA. In Japan they idolize his shoot fighting, and submission skills. Yeah he is pretty old now, but in his prime he would own everyone in his weight class, and even some heavier guys. He is one of the best all around fighters in MMA history.
