If UFC 169 did not exist, we would have to invent it as an example.
UFC 169 flopped from the first online prelim to the last title fight. Of 12 fights, 10 went to decision, the most in UFC history. The most important, a rematch between bantamweight champion Renan Barao (33-1-0) and former champ Urijah Faber (30-6-0), ended with a premature stoppage by referee Herb Dean.
Barao clearly controlled the fight. He dropped Faber with an overhand right and pounded him on the ground. Faber stayed in belly-down side control, and the California Kid was only able to turtle up and cover his face against the barrage of punches Barao threw. Though Faber gave a thumbs up to signal he was surviving, Barao pled with Dean to end the fight.
I think [Dean] is the best referee in the business. He rarely ever makes mistakes, but he made a mistake tonight. Barao gets screwed and Faber gets screwed. It's the cherry on the 10-decision, record-breaking catastrophe this evening.
More than just a boring card, UFC 169 shed light on some issues the promotion will have to deal with moving forward.
