Khan doesn't sniff the top 20 upsets. LW borderline contender w/known weak chin shouldn't even be mentioned in the same breath as one of the most dominant undisputed HW champs in the history of the sport being beaten by someone completely out of left field.
You have to ask? Tyson/Douglas could be the biggest upset in sports history period although the 1980 USA hockey team might argue otherwise.
One more vote for Tyson-Douglas. Hands down #1. Next, it'd probably say Liston-Clay, Baer-Braddock, Ali-Spinks, Ali-Foreman (there's a pattern here). Oh and Robinson-Turpin. Dunno if that's the right order, but I'd say those are all pretty big upsets.
PAc is not fighting a prime Dlh so that won't be the biggest upset. Tyson/Douglass is still the biggest upset in boxing imo.
Good post, even with the semi controvertial decision in the first fight, Jones/Tarver 2 defitnaly deserves a spot as one of the biggest boxing upsets because of how it happened.
