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.
