This highlight knockout happened on December 12, 2015 at UFC 194, as Conor McGregor beat Jose Aldo for the Featherweight Championship. The reason I chose this as my sports gif, is because it was the most anticipated fight of the year. Aldo was undefeated for nine years and dominated his division. McGregor was also undefeated in the UFC at the time and had become a superstar. He not only became popular in the UFC, but in all of sport. His thirteen second knockout was a highlight in every sports broadcast, including ESPN and Fox. What makes it more incredible is that he predicted it, leading up to the fight.
