The Kansas City Chiefs had an interesting 2015 regular season, to say the least, becoming the first team in NFL history to finish with an 11-5 record in a season that included a five-game losing streak, per Elias Sports Bureau via ESPN.com.
Following an impressive Week 1 win over the Houston Texans—Kansas City's opponent in the AFC Wild Card Round of the playoffs—the Chiefs lost five consecutive games to the Denver Broncos, Green Bay Packers, Cincinnati Bengals, Chicago Bears and Minnesota Vikings.
The first three defeats—all to teams viewed as legitimate Super Bowl contenders—may have been excusable, but the Week 5 home loss to Chicago seemingly put the nail in Kansas City's coffin.
Making matters even worse, the Chiefs then lost to Minnesota the following week, thus dropping to 1-5 with a couple of tough games coming up.
Of course, with Roethlisberger out of the lineup, nobody took Kansas City's victory as a sign of things to come.
Even a blowout win over the hapless Detroit Lions in Week 8 didn't draw much attention, but it was finally impossible to ignore the Chiefs when they came out of their Week 9 bye with a 29-13 road win in Denver to improve to a respectable 4-5.
Having survived a tough early schedule, albeit in unconventional fashion, the Chiefs ripped off another seven wins—all against non-playoff teams—to finish at 11-5 with a 10-game winning streak.
Previously, the best record for a team with a five-game losing streak was set by the 1986 New York Jets, a squad that started 10-1 before losing its last five regular-season games.
That Jets team beat none other than the Chiefs in the first round of the playoffs, but then bowed out with a divisional-round loss to a Cleveland Browns squad that was making its second of five consecutive playoff appearances.
