From 1999 on, just for more modern comparisons.

Soto vs Dillashaw?

Kondo even though he is pretty fuckin legit would have been a big win against Wand while he was on his tear.

OSP vs Jones but that was for interim title

Cote or Leites vs Silva

KASINO - Might still be serra gsp

Hillary vs Donald Trump

JoeMimic -

Sad part is if Chael gets through round one he might win because Jones had that toe bone poking out. 

Honestly if he just lasted long enough for the ref to see it, he wins.

He wasn't too far away from being a MW and LHW champ.

Hard to hate a guy who will literally fight anyone anytime anywhere, he tried to fight Fedor on 1 hours notice.

12

GSP vs Serra don't count but Serra was +700 I think (might have been more)
Rousey vs. Holm also doesn't count but Holm was +700 at one point

Biggest I found was 
Bethe Correia vs Rousey as Correia was +1190 at one point

Honorable mentions 
Jones vs Chael as Chael was +800
Soto vs Dillashaw, Soto was +900
Johnson vs Elliot as Elliot was +700

13

maia vs silva ufc dubai

14

I remember Chad mendes being a huge favorite over Cody Mckenzie.

This.

The triangle Chael hit was incredible, and came out of nowhere. Biggest title upset in UFC history.
I spilled my beer EVERYWHERE

serra beating GSP was the biggest upset ever. despite the betting lines and what odds say, all the hardcore fans jaws dropped when gsp was tko'd.

 

ronda and holly isnt even that much of a upset as we all knew ronda had shit stand up but GSP was truly better than serra in every single way. even matt hughes said serra got lucky. EVERYONE said serra got lucky. then serra "got injured" prolonged his title reign to a year or so, and then  GSP wiped his ass with him in the rematch.

"ronda and holly isnt even that much of a upset as we all knew ronda had shit stand up"

Not everyone knew

AnthonyWeiner - Fedor was a 12:1 favorite over Werdum.


No way. It was kind of close-ish. A lot of people bet Werdum at +300. I think Choi and Rizze were +800 against Fedor. Something ridiculous like that.

Anderson vs DC.
