This Saturday, the UFC returns to São Paulo, Brazil, having hosted four events in four different continents in the last four weeks.

In the main event, Jan Błachowicz (24-8 MMA, 7-5 UFC) faces former Strikeforce middleweight champion Ronaldo ‘Jacaré’ Souza (26-7 MMA, 9-4 UFC) in what will be the Brazilian’s first foray at light-heavyweight.

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

Błachowicz notched a second-round submission win over Nikita Krylov before having his four-fight winning streak snapped by a third-round TKO defeat to Thiago Santos. The Pole returned to the win-column in July, defeating Luke Rockhold via second-round KO.

This will be the second fight in a row that Błachowicz finds himself facing a former Strikeforce middleweight champion stepping up to light-heavyweight for the first time in their career.

Jacaré earned consecutive Fight of the Night bonuses in a split-decision defeat to Kelvin Gastelum and a third-round KO over former UFC middleweight champion Chris Weidman. Jacaré last fought against Jack Hermansson, coming up short in a five-round unanimous decision defeat.

Jacaré, who turns 40 in less than a month, holds career victories over three former UFC champions yet has never held UFC gold himself.

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

The two men share just one common opponent; former Strikeforce and UFC middleweight champion Luke Rockhold.

Błachowicz defeated Rockhold via second-round KO in July, whilst Jacaré suffered a unanimous decision defeat against Rockhold back in September of 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 Fight Night 164: Jan Błachowicz vs. Jacaré Souza checks in with a score of +6.

This score ranks joint-30th out of 46 UFC events in the last year, or 15th out of 25 Fight Night events in the same period.

Here’s a look at how this score compares to other events’ scores over the past year:

As you can see, this score falls short of the +12.1 average for all events in the last twelve months, as well as the +8.4 average for Fight Night events in the same time frame.

Let’s take a look at exactly how this score breaks down:

The highest individual contributors to the score are Charles Oliveira and James Krause (both +5), whilst former UFC bantamweight champion Renan Barão (-4) is the lowest scorer. Three fighters will be making their promotional debuts on this card.

Enjoy the fights!

Update: Following Veronica Macedo’s withdrawal, the score now stands at +5.
