Barret Robbins, Oakland Raiders

Where: Super Bowl XXXVII, San Diego (2003)
Incident: Twenty-four hours before the game, Robbins, who had a history of depression, disappeared from the team hotel and ended up going on a drinking binge in Tijuana, Mexico, claiming he was so delusional that he thought the Raiders had already won the game.
Result: After Robbins resurfaced as an incoherent mess, he was sent home and ended up watching the Tampa Bay Buccaneers blow out his team, 48-21, from a San Diego hospital. He must have been having delusions again when he later said that if he played in the game, he felt the Raiders would've won.
