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: Vadim Nemkov SD(3) Phil Davis
Nemkov, a virtual unknown, manages to take a close decision over the perennial Top 10, Phil Davis.
Most Lopsided: Jared Cannonier TKO(2) David Branch
About 2.5 years prior, Cannonier fought at 241 pounds. Here, in his Middleweight debut, pulled off quite an impressive upset.
