You're adding emotion into the judging. Emotion invokes impartiality. This is not about deserving or anything else. This is about judging impartially within the rules. Who did the most, and succeeded the most should have been the only deciding factor when declaring a winner. It really is as simple as that.
I think you are adding a factor that has no bearing on the fight. The abilities of the fighter and how they used them are not factors when judging. You can only judge what actually happens in the ring. On saturday night. No matter how boring you may feel the fight was. Shogun did more of everything he needed to do to win and they judged against him. They disregarded what actually happened in the ring, and made a decision that would seem to be either colluded or emotional. Neither of which should happen.
