10 Biggest upsets in WWE history

Guerrero slays the Beast

During his initial run with the WWE, Brock Lesnar was booked pretty much like he is booked these days. He was a monster that no one wanted to rub shoulders with and thanks to the great booking that Paul Heyman did on SmackDown, Lesnar had a great credibility. This is why all the opponents that faced Brock became underdogs.

Eddie Guerrero was no different. In the No Way Out pay-per-view before WrestleMania XX, Eddie faced off against Lesnar for the WWE championship. The contrast of the styles produced a great match between these two and the ending was the cherry on the top as Eddie closed out the PPV with the title.
