I'm pretty positive Jackson was quite a favourite against Graham.

He was definitely the favourite,for the simple reason he showed us in the fight,he had brutal fight changing power

[A-Wolf]

All the times fighters with huge flocks of fangirls got collectively shut up.

floyd-ortiz. ortiz was a young lion! can't believe floyd won. what a miracle. like ali-foreman.

[G22]

Not really a favorite per say, but Hasim Rahman vs Lennox Lewis I and II!

Lewis was odds on favourite to win both fights so only the 1st fight was considered an upset

My favourites were
Khan - Prescot
Mosley - Margarito
Holyfield vs Tyson
Garcia - Khan

[ajohnz]

Mosley vs Margarito, Hopkins vs Trinidad, Mayweather vs Corrales.

and a star is born. only time in his career he was "underdog"?
