The Broncos offense picked a heck of a day to go in the tank. Perhaps there’s some logic in the fact that neither offense — led by coaches with a combined 400-plus NFL wins — looked particularly sharp. But Denver was more than a little bit funky at Arrowhead Stadium. Russell Wilson threw for 95 yards. The Broncos turned the ball over three times. They’ve got a dangerous run game but went 53-plus minutes without scoring and had to bail on it altogether. After a hot start to the season, Wilson’s cooled considerably the past two weeks. But this was by far his worst outing of the season.
