Re: bjj vs wrestling which one is more effective?
Both are effective, in their own right. I say BJJ gives you the better chances of a submission finish. Wrestling gives you the better chance for a decision.
A BJJ practitioner can spend the entire fight on the bottom of a wrestler -- the BJJ practitioner has the better chance for a finish (the wrestler does not from his wrestling, alone), but if he doesn't get it, the wrestler's chances for a win via decision are at its highest.
