This Saturday, the UFC marks its 500th event by introducing a championship belt that is not associated with a specific weight class for the first time since 1995.

The BMF belt will be on the line as Jorge Masvidal (34-13 MMA, 11-6 UFC) takes on former UFC lightweight title contender Nate Diaz (20-11 MMA, 15-9 UFC) in a contest between two of the most popular fighters on the UFC’s roster.

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

Masvidal rebounded from a three-round decision loss to Stephen Thompson with a second-round KO over Darren Till, picking up the Performance of the Night and Fight of the Night bonuses in an eventful few hours which also saw Masvidal get into a backstage altercation with Leon Edwards.

In his next contest, Masvidal defeated Ben Askren with a spectacular flying knee KO in just 5 seconds- the fastest knockout in UFC history.

After going 1-1 in two fights against Conor McGregor (winning via second-round submission before losing a majority decision verdict), Diaz took a three-year hiatus from the sport.

He returned to action in August, scoring an impressive three-round decision victory over former UFC and WEC lightweight champion Anthony Pettis.

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 Masvidal fared against any shared opponents and on the right, you’ll see Diaz’s results against the same men.

The two men share two common opponents; Donald Cerrone and Benson Henderson.

Both men suffered five-round decision defeats to Henderson, although one judge gave Masvidal the nod in his contest against the former UFC and WEC lightweight champion.

Masvidal scored a second-round TKO victory over ‘Cowboy’ in 2017, whilst Diaz defeated Cerrone via unanimous decision in a dominant display back in 2011.

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 244: Jorge Masvidal vs. Nate Diaz checks in with a strong score of +31. This score ranks 3rd out of 46 UFC events in the last year, with only 18 of 499 events in promotional history scoring higher. Here’s a look at how this score compares to other events’ scores over the past year:
