KANSAS CITY, Mo. (AP) — Everything has changed in the last three weeks for the Kansas City Chiefs. In the nine weeks prior their bye week, the Chiefs had rolled to a 9-0 record, an unimaginable turnaround from a 2-14 finish a year ago. The defense was holding opponents to just 13.3 points per game, and the offense was playing nearly mistake-free football.

After a pair of losses to the Broncos sandwiched around a heartbreaking defeat to the Chargers, the Chiefs not only have watched the AFC West lead slip away, they’ve also become the first team in NFL to win its first nine games and then lose three in a row.

It is gut-check time for the Chiefs, who play at Washington this Sunday.
