The reason why you won't see any Valente students as champions in any mma events or any jiu-jitsu sporting events, is because they feel when you train for these events with rules, you are seriously asking for trouble when you get in a real street-fight with no rules. They do not compete in any way, shape or form.
yea.. i guess Royler jiu jitsu isn't "street effective" because him and his students compete in mma/bjj/adcc..... :S
