KANSAS CITY, Mo. (AP) — Patrick Mahomes threw a 25-yard touchdown pass to Demarcus Robinson with just under two minutes. Then the Kansas City Chiefs watched as Pro Bowl kicker Younghoe Koo missed the tying field-goal try with 9 seconds left to give them a 17-14 win over the Atlanta Falcons and the No. 1 seed in the AFC playoffs.
