in 2003 and their offense, considered by many as one of the most powerful of all time, helped make Kansas City again a favorite to win Super Bowl XXXVIII. After starting 9–0, the Chiefs lost to the Cincinnati Bengals in their tenth game following a "guarantee" by Bengals wide receiver Chad Johnson. The Chiefs' dream season of 2003 began to lose momentum by November, but they still managed to gain the number two seed in the 2004 playoffs. The mighty homefield advantage of Arrowhead Stadium and their high-powered offense wouldn't lead the Chiefs to glory and the Chiefs lost to the Indianapolis Colts in the AFC Divisional playoffs in an offensive shootout in which neither team punted, an NFL playoffs first.
