The old adage says “Time flies when you’re having fun.”
And somehow, it’s already been a decade since one of the UFC’s breakout years – 2015. The year featured all kinds of big news.
That year, long-reigning champs like Ronda Rousey, Jon Jones and Chris Weidman all suffered downfalls – either through title losses or, in the case of Jones, the removal of his title after a felony hit-and-run.
The year also saw the true rise of Conor McGregor, the arrival of Joanna Jedrzejczyk with three title wins, and Rousey had two stellar title defenses before her upset loss to Holly Holm. And to go along with the big ones, there were great ones.
The UFC has put together its favorite fights from 2015, and there’s a 2-hour marathon of all-time classics to sift through ahead of the return to regularly scheduled live MMA in a week. Check out the video above, and more coverage of the standout fights from 10 years ago below.
