In the Super Bowl era the Chiefs are the 32nd team to start 7-0. All of the previous 31 teams made the playoffs and 15 reached the Super Bowl.
While it’s unlikely Kansas City does something crazy and loses one or fewer games like five of the teams (2011 Packers, 2007 Patriots, 1998 Vikings, 1985 Bears and 1972 Dolphins), only two of the teams lost five games the rest of the season – 2000 Vikings and 1985 Rams.
