There’s an old maxim that “good things come in threes”, which anyone who has sat through the third part of the Back to the Future, Rocky and The Godfather trilogies will have solid ground to disagree with. But just occasionally triple headers can deliver the goods, and the hope is that Stipe Miocic and Daniel Cormier’s third encounter adds to that pantheon.

The Heavyweight Championship will be on the line when the two are scheduled to meet at UFC 252 on August 15 in the UFC’s APEX production facility in Las Vegas, but there’s much more than just gold and bragging rights at stake here.

This one is for all the marbles. 1-1, both knockouts but great fights, I can’t wait to fight this dude again!! Now it’s time to work as hard as I ever trained. #weareaka #zinkinsportsmanagement #2xheavyweightchamp 2xlightheavyweightchamp pic.twitter.com/BvyhectS4X

The following table shows the peak quarterly ranking of all fighters to make their UFC debut in 2020 as well as the corresponding ranking of their debut opponent. The fighter with the highest peak ranking was former Invicta FC champion Jinh Yu Frey. However, her highest ranking, #2 Women’s Atomweight, came in a division not currently promoted by the UFC. So far this year, 10 fighters have made their promotional debut against a fighter whose peak ranking was in the top 25. In those fights, debuting fighters have gone 3-7. UFC rookies have gone 17-22 overall in their debut fights.
