Wow. That was incredible to see. I honestly thought I was going to get Rick Rolled or something... I had no idea this footage existed.
I believe that Rolls' death was a tragedy for not just the Gracie family, but BJJ itself. His interest in incorporating the best of other grappling styles into BJJ has always struck me as the antithesis of Rickson's rhetoric about the "purity" of his jiu-jitsu. If Rolls were alive today, our sport might look different. It's a shame we'll never know how his innovative style would have evolved.
Sigh. Rafa Mendes better not go hang gliding! Ever!
