I think he is referring to times where it appears they give the bonus to the bigger name fighter in the main or co main event. for example lesnar's basic arm triangle getting it over lytle's crazy inverted armbar from full mount at ufc 116.
It has happened quite a few times. Another one is how GSP/Fitch received the fight of the night when Maia/MacDonald clearly earned it. GSP/Fitch was barely a fight, it was just a one-sided beat down.
