Best possible way this ends: Pioli is fired, Cassel is traded for a 2nd round pick, Clark Hunt records an apology that plays on the video boards before every home game and Deb graduates from a 12-step program after joining Alcoholics Anonymous. The first Red Friday in 2013 features a dummy in a #7 jersey being burned in effigy, which becomes a tradition, not unlike Guy Fawkes Night in Britain.
Worst possible way this ends: The Patriot Way's elite hackers gain control of the planet, logs all of the IPs, cross references them with the IP list for anyone who has purchased a ticket to a Chiefs game, and bans all of those people from Arrowhead for life. Deb is gifted George Blowfish's seats for life. The Planet is destroyed forever due to a constant stream of DDoS attacks originating from the Boston area. The pilot loses his license.
The Chiefs will finish 5-11, Alex Smith will play horribly, and Geno and I will cackle with glee while he burns Kansas City.
