Small wonder, either. After getting the players' choice Romeo Crennel as head coach and returning four of their top players from season-ending injuries, the Chiefs looked poised to challenge for the AFC West divisional title.
Instead, Kansas City's put together one of the most embarrassing stretches of play in recent memory.
The Chiefs have yet to lead in a game despite winning against the New Orleans Saints. Four of their five losses were by double-digit deficits and half of their 10 meager touchdowns came in the fourth quarter with the game out of reach.
