KANSAS CITY, Mo. — The last time the Chiefs hosted the Indianapolis Colts in the playoffs, the day broke sunny and mild, with barely a breeze. On his drive to Arrowhead Stadium that January morning in 2004, Kansas City quarterback Trent Green, hoping that a rainy chill would greet the visitors from a domed stadium, rued the weather.
“I knew we would have to score a bunch of points,” Green said.
The Chiefs, the highest-scoring team in the N.F.L., did: 31, a nick above their season average, and never punted.
