My point exactly. I HATE to see a soo called bjj black belt getting pounded because he doesn't use his strong point. If Roger know his stand up suck, why would he want to stand up? And once again, being a black belt, he can't find a way to take the fight to the ground?? Kennedy look like more of a grapller than Roger in this fight. And being 6'5" can't he pump out those jabs more???
Y'know... As great as rubber guard is, that was Frankie Edgar in his guard. The guy knows a thing or two... Also, I would be amazed to learn that Oliveira isn't aware of RG.
If you are saying Frankie Edgar is unsubmitable in any guard then your point is valid. No guard works 100% of the time but RG eliminates GNP and Frankie was basically giving up Free New York.
Being aware of RG and being proficient at RG are two different things.
