McGregor comes fifth overall and tops the list for the “Sports Figure” category in Fansided’s annual Fandom 250 ranking. In 2016, McGregor was ranked at number 147 on the list. The only sports celebrity higher in the ranking is Dwayne “The Rock” Johnson. Fansided says one of the biggest factors for the ranking was how McGregor dominated headlines in the media worldwide with his fight against Floyd Mayweather.
The numbers support this. Mayweather vs. McGregor is a top-two most watched pay-per-views in combat sports history and was already the biggest draw in UFC history entering the year. McGregor’s newborn son gained tens of thousands of Instagram followers the day he was born. In a 12-month stretch leading into the fight against Mayweather, McGregor added 13 million followers on social media and his posts generated 419 million interactions.
