Chiefs Clinch West

Alex Smith threw for 304 yards and a touchdown, Kareem Hunt ran for 91 yards and a score and the Kansas City Chiefs beat the Miami Dolphins 29-13 on Sunday to clinch back-to-back AFC West titles for the first time in franchise history.

Tyreek Hill had six catches for 109 yards, and Harrison Butker converted five field goals, as the Chiefs (9-6) dashed what faint postseason hope the Dolphins (6-9) still harbored.

Jay Cutler threw for 286 yards and a touchdown, but a chunk of that came on a 65-yard toss to Jakeem Grant late in the first half. Otherwise, Miami struggled against a Chiefs defense that has been stingy and opportunistic the past two weeks.

That’s coincided with the return of Marcus Peters from his disciplinary suspension.

The Chiefs’ star cornerback had two interceptions and forced a fumble against the Chargers last week, a win that pushed them to the brink of the playoffs. He recovered a fumble and forced another on Sunday, giving Peters a hand in five turnovers the past two weeks.

Both turnovers led to points, but they weren’t the Dolphins’ only costly miscues.

They also were nailed for defensive holding four times, all of which came on three scoring drives for Kansas City. And the Dolphins inability to get off the field on third down, after holding opponents to 8 for 39 the past two games, was similarly deflating.

Still, the Dolphins had the ball trailing 17-13 late in the first half, the outcome and their longshot playoff hopes were still in the balance. But they soon went three-and-out and the Chiefs added a field goal to make it 20-13 at the break, then another to start the second half.

Even when the Dolphins made a crucial stop on fourth down to get the ball back later in the third quarter, they squandered the opportunity. Peters stripped Kenny Stills to give the Chiefs the ball, and Butker hit his fourth chip-shot field goal for a 26-13 lead with 12:19 to go.

That gave a sparse crowd that turned out on Christmas Eve, braving slick roads from an overnight snowfall frigid wind chills at kickoff, plenty of time to celebrate a division title.

Turn their thoughts toward a home playoff game in the new year, too.
