I have my theory. If you put someone that is emotionally involved as we (the fans) are, then you throw away the objectivity. A karate fan will always give the fight to Machida. A college wrestler who nearly went to the Olympic will always give the fight to Dan.
We can't have these people as judge, it will be WORSE. Of course, we can't have people that know nothing about MMA either. Very, very tough call. We have to chose the least of two evils. Given the choice, I'd rather have a guy that knows the rules but don't know the fighters AT ALL. I want people aware of MMA rules that can't spell gustafsson on command and wont tell me all the martial arts mastered by Machida. I want a guy that will say "Machi-who? Never heard of him. Is he good at Wrestling, grappling, boxing? What does he do for a living?" That's the guy I want as a judge. Unfortunately, there are very few of these guys...
When I heard Almeida was getting his judging license, I was as enthusiast as I was skeptical. You can't ask him to judge any Gracie affiliated fighter! He's been Gracie affiliated since his childhood! Do you know how many Gracie affiliated fighters there are in the UFC? DANG! (as a Gracie would say)
So we solved nothing. The most potentially competent judge can only judge 10% of UFC fights. Very odd situation if you ask me.
