I guess I am the only person who feels a little differently. I think the point of MMA rules is to come as close to a real cagefight as the athletic commissions will allow. Obviously, head butts and eye gouges take away from the sport, and soccer kicks to the head of a grounded opponent are not going to happen. But in a real fight, if you are good enough to slice someone's head open with an elbow so they can't see from all the blood in their eyes, then you are good enough to finish their blind ass shortly thereafter. The only reason it is stopped before that is that there are chemicals in blood that cause blindness if left in the eyes for even short amounts of time, and nobody wants to watch a career disappear because of that.
I think the real issue, as usual, is shitty reffing and judging. If someone is landing short elbows for show from guard, call it what it is and stand them up. If the elbows are doing damage, then they stay. Tough shit for all the guys who don't like it - if it is effective, learn to stop it. But I find it funny that after all that, Gil Melendez used elbows to end the fight in a brutally exciting way, and even outspoken Nick Diaz threw a few on the feet. The point is, don't take out one of the body's primary striking surfaces ... shoot Cecil Peoples and everybody like him and make sure that refs take careful looks at how effective each elbow really is.
