Event: UFC 46 1/31/2004
Winning Move : Rear Naked Choke
Hughes was a living legend at the time. His record stood at 35-3 with a 13-fight winstreak. No one could touch him in the welterweight division. Penn was a lightweight and when it was announced he was moving up to fight Hughes, Hughes called Penn disrespectful.
If you want to be the man, you have to beat the man. Never was that demonstrated more emphatically than when BJ "The Prodigy" Penn snuffed Matt Hughes at UFC 46.
