The biggest UFC event of the year, topped by three championship bouts, is a little over 24 hours way.

In the main event, welterweight champion Kamaru Usman (15-1 MMA, 10-0 UFC) defends his title against bitter rival and former interim welterweight champion Colby Covington (15-1 MMA, 10-1 UFC).

In the co-main, Max Holloway (21-4 MMA, 17-4 UFC) puts his featherweight title on the line against rising contender Alexander Volkanovski (20-1 MMA, 7-0 UFC).

And in the third title-fight of the night, bantamweight champion Amanda Nunes (18-4 MMA, 11-1 UFC) faces former featherweight champion Germaine de Randamie (9-3 MMA, 6-1 UFC) in a rematch of their 2013 bout.

Let’s take a look at the last three results of the two men in Saturday night’s main event:

Both Usman and Covington followed unanimous decision victories over Demian Maia and Rafael dos Anjos with a five-round decision win against a former UFC welterweight champion.

Usman dethroned Tyron Woodley to claim the title for himself in March, whilst Covington defeated Robbie Lawler in a dominant display in August.

Here’s a look at how these two fighters fared when competing against common opponents shared throughout their careers. On the left of the graphic, you’ll see how Usman fared against any shared opponents and on the right, you’ll see Covington’s results against the same men.

The two men share four common opponents; Jose Caceres, Warlley Alves, Demian Maia and Rafael dos Anjos.

Caceres, brother of UFC’s Alex Caceres, is responsible for the sole defeat in Usman’s MMA career, a first-round submission in May 2013. Covington defeated Caceres via unanimous decision less than a year later.

Alves, on the other hand, is responsible for the sole defeat in Covington’s MMA career, again via first-round submission, in December 2015. Usman defeated Alves via unanimous decision less than a year later.

Both Usman and Covington notched unanimous decision victories against Maia and dos Anjos.

Let’s take a look at the last three results of the two men in Saturday night’s co-main event:

Holloway notched a fourth-round TKO victory over Brian Ortega before suffering his first defeat in fourteen fights in a unanimous decision loss to Dustin Poirier. The Hawaiian returned to the win column in July with a unanimous decision victory against former UFC lightweight champion Frankie Edgar.

Volkanovski followed a unanimous decision win over Darren Elkins with a second-round TKO against Chad Mendes, before scoring the biggest victory of his career to date with a decision victory over former UFC featherweight champion José Aldo.

Here’s a look at how these two fighters fared when competing against common opponents shared throughout their careers. On the left of the graphic, you’ll see how Holloway fared against any shared opponents and on the right, you’ll see Volkanovski’s results against the same men.

The two men share just one common opponent; José Aldo.

Holloway has fought Aldo twice, winning via TKO in the fourth minute of the third round on both occasions. Volkanovski recorded a three-round unanimous decision win against Aldo in May.

Now let’s take a look at the last three results of the two women in Saturday night’s bantamweight title fight:

Nunes scored a fifth-round TKO against Raquel Pennington before handing Cris Cyborg her first defeat (a first-round KO, no less) in thirteen years to claim the UFC featherweight title. Nunes last fought in July, defeating former UFC bantamweight champion Holly Holm via first-round TKO.

De Randamie became the inaugural UFC featherweight champion in February 2017 after a controversial decision victory over Holm. After a prolonged absence that saw her title stripped from her, de Randamie returned with a unanimous decision win over Pennington and a sixteen-second TKO victory against Aspen Ladd.

Here’s a look at how these two fighters fared when competing against common opponents shared throughout their careers. On the left of the graphic, you’ll see how Nunes fared against any shared opponents and on the right, you’ll see de Randamie’s results against the same women.

The two women share four common opponents; Vanessa Porto, Julia Budd, Raquel Pennington, and Holly Holm.

Nunes scored TKO/KO wins against Porto and Budd, two opponents who got the better of de Randamie via submission and unanimous decision, respectively.

Both women notched victories over Pennington and Holm, although de Randamie went the distance with both fighters whilst Nunes finished them both.

The Dwyer Score Each event, I calculate a ‘Dwyer Score’ for the card. It essentially gives a numeric value to the momentum of fighters competing at any one event. I do this by assigning a figure to each fighter’s current streak; a fighter on a five-fight winning streak contributes +5 to an event’s score, whilst a fighter on a two-fight losing streak contributes -2 to the score. Only UFC results are considered and a fighter coming off a no-contest, a draw, or a bout with another promotion has a streak of 0. When you tally up the scores for every fighter on a card, you get a total for the event- the ‘Dwyer Score.’ This score does not claim to predict or measure the quality or excitement of any one card, but it does give you an idea of the general momentum of fighters heading into a specific event. The graphic to the above-right displays some of the highest-scoring events of all time, to help give some context to this score. UFC 245: Kamaru Usman vs. Colby Covington checks in with a huge score of +54. This score ranks 2nd out of 504 UFC events in promotional history, with only UFC 194 scoring higher. Here’s a look at how this score compares to other events’ scores over the past year:
