This Saturday, the UFC kicks off the new decade with the return of the biggest star in MMA.

In the main event, former UFC lightweight and featherweight champion Conor McGregor (21-4 MMA, 9-2 UFC) takes on Donald ‘Cowboy’ Cerrone (36-13 MMA, 23-10 UFC) in a 170 lbs. contest.

Cowboy has competed 11 times inside the Octagon since McGregor last notched a UFC victory, back in November 2016.

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

McGregor scored a majority decision victory over Nate Diaz in his last welterweight contest back in August 2016, before defeating Eddie Alvarez via second-round TKO to become the first fighter in UFC history to concurrently champion two divisions.

The Irishman returned to the Octagon in October 2018, losing via fourth-round submission against UFC lightweight champion Khabib Nurmagomedov.

Cerrone notched a five-round unanimous decision victory over Al Iaquinta last May before suffering consecutive TKO defeats against Tony Ferguson and Justin Gaethje.

The holder of the most victories in UFC history, Cowboy has picked up five fight-night bonuses in his last five fights.

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

The two men share three common opponents: Dennis Siver, Eddie Alvarez, and Nate Diaz.

Both men scored early stoppages over Siver, whilst Cerrone had to settle for a decision victory against Alvarez- an opponent McGregor finished.

McGregor and Cerrone each suffered defeats against Diaz, via submission and unanimous decision respectively, although McGregor also holds a majority decision win over the Stockton native.

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 246: Conor McGregor vs. Donald ‘Cowboy’ Cerrone posts a relatively low score of +6. This is a significant decrease from the +36 average held by McGregor’s seven previous Pay-Per-View features. This score ranks joint-30th out of 43 UFC events in the last year, and 12th out of 13 Pay-Per-View events in the same period. Here’s a look at how this score compares to other events’ scores over the past year:
