I'm not talking about the fights where the underdog scores a KO on a "lucky punch" or anything like that.

I'm talking about fights where the big underdog absolutely dominated the favorite in a way that would suggest that the underdog was CLEARLY the better fighter going in and make the oddsmakers say "WTF was I thinking."

Thinking along the lines of a Jeff Lacy/Joe Calzaghe situation, where the underdog just eats the favorite's soul in the ring.
