When Jon Jones vs. Alexander Gustafsson was booked in September 2013, nobody thought the Swede stood much of a chance against the light heavyweight champion, whom many were already calling the greatest mixed martial artist of all time.
But the two went toe-to-toe for 25 back-and-forth minutes in what ended up being one of the best scraps in the history of the sport. In hindsight, it was a can't-miss fight.
Thankfully, the two will rematch later this year at UFC 178, in what is one of the 12 can't-miss fights left in 2014. But where does it rank? And what are the other 11 fights you want to make sure you see live?
Keep in mind, the UFC is far from done booking fights to fill out the 2014 lineup, and this is a ranking based on what is currently on the books.
