Kansas City Chiefs and Denver Broncos essentially ended on a Jamaal Charles run. Had the Chiefs ran the ball earlier in the game in situations that called for it, the final stretch of events would have likely never occurred.
With less than a minute remaining and the score tied, Charles fumbled and Broncos cornerback Bradley Roby returned it 21 yards for a touchdown. Denver went up 31-24 after Brandon McManus' extra point, and the Chiefs lost by that count.
Trying to take the game into overtime was the right decision for the Chiefs, but kneeling on the ball would have made more sense.
