UFC 321 Previews

The UFC 321 card will feature thirteen bouts, all of which will be previewed in this post. The card will be headlined by a bout for the undisputed heavyweight championship between reigning champion Tom Aspinall (pictured top left) and former interim champion Ciryl Gane (pictured top right). The co-main event will be for the vacant women’s straweight title. Brazilian contenders Virna Jandiroba (pictured lower left) and Mackenzie Dern (pictured lower right) will face off in that bout.

A fighter’s CC win probabilities are based off of a fighter’s Cage Calculus (CC) Rating and their place in the CC Rankings. A fighter’s CageCalc+ Score is determined by a variety of factors and is specific to each matchup. The CageCalc+ projection is an estimated win probability based on this statistic. Each fighter’s new CC Ratings after their bouts will be determined by the first CC win probability only.

Also featured below their record and rating is their divisional rankings in the CC Rankings and the official UFC Rankings. Any fighter falling outside of the top 15 of their respective division is classified as NR (not ranked).

Also displayed to the right of their rankings is a fighter’s CCz Score. A positive CCz Score indicates a fighter is above average for their weight class. A negative one indicates they are below average. The higher the number is, the farther away from average a fighter is (in either direction). CCz Scores typically range from as high as positive 4, to as low as negative 2.5.

The fighter’s name highlighted in green at the bottom of the panel indicates the editor’s pick to win. The numbers above each fighter’s name indicates their posted odds to win on FanDuel Sportsbook as of the posting of these previews.

Without further ado, here is the Cage Calculus tale of the tape for this week’s fights!
