Greatest Underdog Fighter/ Most Upsets

This guy we were talking about the other day, Bolotniks, does not seem to understand very well what the word "underdog" means either.
I like his boxing skills and how he uses his chances.

EDIT: I see cst already mentioned him. Well, I agree with cst then.

 

fights results prediction survey pools and betting underdog.
examples: Ruiz vs A.J 1 st fight, Pulev vs A.J etc.

there for example tapology survey with predictions for these Bolotņiks fights.
