I saw a video recently by Rener and Ryron where they talked about the differences of their self defense jiu jitsu and sport jiu jitsu. They quoted one of the Valente Brothers who said something to the effect that the two are as different as apples and bowling balls. I am not asking this to get into a debate about SD vs sport, as that has been discussed here many times. What I am curious about is - is the bjj in Ralph Gracie's instructional similar or the same as the bjj taught at Gracie Academy and at Valente Brothers? I ask that b/c the bjj on Ralph's instructionals is very different from what is taught at my gym (RMNU).
