He was probably banking on Manning not having a functioning neck, the Chargers to be... well, the Chargers, and the Raiders to be involved in some massive felony that leads half of them to be arrested.
In other words, probably not that hard of a guess that the Chiefs would suck the least, even though I disagree and felt that Manning's Broncos would have it even if he needed to wear a neckbrace throughout the season.
Only the Chiefs could play 8 games, not lead in regulation a single game, yet somehow have a win.
Gotta love game winning Field Goals in OT. That's almost as impressive as a couple years ago when the Raiders became the first team in the NFL to win all of their division games, yet not make the playoffs. What is it about that division anyway?
