If you take them down and dominate them, that's their fault for not having better defense, sweeps and escapes. As for him not using BJJ in a BJJ competition, Jeff Monson and Amaury Bitetti have won on points in BJJ and nogi grappling by dominating position due to their strong wrestling skills so I don't see how this is different. We may all love subs but if a guy is able to win on points and avoid dangerous situations, I'm not gonna begrudge him that because I'd do the same if I was able to. Don't feel bad. Just win, baby. Just win.
