We detailed our intentions to add some alternate rating systems for comparison in a previous post.

We got several comments and questions about this, with two common questions being:

1 – I thought the system in use was a version of Elo?

2 – What’s the point of adding alternate rating systems?

Addressing #1, the current rating system does share a few things with Elo, most notably, the core formula that manages the movement.  However, it has also borrowed elements from the Glicko rating system and has tons and tons of additional code in place to make it better equipped for MMA, which is still a very disorganized and unpredictable sport, in terms of not only the matches but the matchmaking as well.  Systems like Elo and Glicko were made for chess, a sport (game?) where competitors can play dozens of matches in a month where none of them get kicked in the head by their opponent.

On the topic of Darren Till coming in overweight again, I’ve seen more than a few instances of people citing statistics where fighters won at an astoundingly high rate in bouts where they missed weight.

Acquiring good data on MMA is hard enough, so we don’t have specifics on the intended divisional limit for all bouts.  However, we do have a ton of bouts with weigh-in data for both fighters.

I first retrieved a count of all pro MMA bouts that ended in a win, where we have actual weigh-in data that shows that both fighters were between 100 and 212 pounds (26,383).  The idea here is to exclude instances of bad data and Heavyweights.

Of these, I then looked at bouts where one fighter weighed between 1.75 and 6 pounds more than the other fighter.  This range seems arbitrary, but I was trying to avoid “freak show” type of matches, while also excluding cases where one fighter may be 169.5 and another at 171 (for example).  I got a surprisingly high count — 5,719.

Of these 5,719 bouts, the heavier fighter won 3,120 – 54.55%

When I change that window to a range of 1.25 pounds to 5 pounds, the win rate changes to 55.14%.

As a recap, most “Fighter of the Year” awards on other sites are really “Breakout Fighter of the Year” awards in that fighters who win, were usually not top fighters in the beginning of the year, but became so by the end of the year.

A fighter like this can and has won our FotY awards, but our award is more about maintaining a high standing during the award year by performing well a sufficient number of times and against a sufficient quality of opponents.  It is more comparable to a season MVP in major team sports, not a playoffs/surprise MVP.

Winners (Tie): Demetrious Johnson, Max Holloway

A very tight call, too tight to call… so we’re going with co-winners for the first time.  DJ gets the nod with the #1 ranking for all 365 days, while Holloway twice beat an all-time great, albeit the same fighter.

3rd Place: Tyron Woodley

Like DJ, Woodley keeps churning out the quality performances and reigns over an even deeper division.  But this year, he takes a backseat to DJ and Holloway.

Winner: Cristiane Justino

With her win over Holm, Cyborg is right on Rousey’s heels for the title of best female MMA fighter ever.  For now, she’ll have to settle with being the best of 2017.

Runner-Up: Rose Namajunas

Rose was looking like the winner, right until the last weekend of the year.

3rd Place: Livia Renata Souza

Winning more than once and being one of the best fighters outside of the UFC is good enough to earn Souza the third position.

Men: Shamil Amirov

A 3-0-1 career record along with a draw against Rousimar Palhares, earns Amirov the award.

Honorable Mentions: Askhab Zulaev

Women: Liliya Shakirova

Soviet-based fighters tend to win these awards, due to their aggressive early matchmaking.  Shakirova’s competition is suspect, but I could see her landing a Flyweight spot on a lackluster Asia/Europe UFC card.

Honorable Mention: Sunna Rannveig Davidsdottir

Most Improved Fighter of the Year: Volkan Oezdemir

With an ascent similar to that of Junior dos Santos, Oezdemir came out of nowhere to become a title contender in the UFC.

Note: We have two ways that we derive biggest “upsets” based on points difference between winner and loser.

“Most Noteworthy” (X minus Y)
“Most Lopsided” (X divided by Y)

Most Noteworthy: Francis Ngannou KO(1) Alistair Overeem

More of a guard change than an upset.  Nevertheless, Ngannou made up a massive point difference in taking Overeem out.

Most Lopsided: Volkan Oezdemir SD(3) Ovince St. Preux

Were the actual outcome a part of this, Emmett/Lamas would get the award.  However, this is about proportional point differences and Oezdemir wasn’t even on the map before this fight.
