In spite of being the most active judges in 2015, Sal D'Amato, Derek Cleary and Chris Lee still managed to be the least controversial, as defined on the list of the 2015 Most Disputed Decisions.

The judge making with the biggest increase in decisions was Derek Cleary. Cleary submitted 17 more UFC scorecards in 2015 than in 2014.
