Plays that defined the season: stopping 'Beast Mode' on fourth-and-1

KANSAS CITY, Mo. -- Here is the sixth in a series of 10 plays that shaped the Kansas City Chiefs’ 2014 season. We’re going in chronological order, not in order of importance.

Stopping the opponent’s running game was difficult for the Chiefs most of the season and the Nov. 16 game against the Seattle Seahawks was no different. They allowed 124 yards that day to Marshawn Lynch, who wound up the season as the NFL’s fourth-leading rusher.

But for one shining moment in the fourth quarter, the Chiefs were up to the task of stopping Lynch. His fourth and one run from the Chiefs’ 36 with less than four minutes remaining never had a chance. The Chiefs, led by linemen Jaye Howard, Dontari Poe and Allen Bailey and linebacker Josh Mauga, swarmed Lynch for no gain, allowing the Chiefs to preserve a 24-20 lead.

That play, combined with two other fourth-down stops in the fourth quarter, allowed the Chiefs to beat the defending Super Bowl champions, win their fifth straight game and tie the Denver Broncos for first place in the AFC West with a 7-3 record.

At that point, all things looked possible for the Chiefs. They had beaten the Seahawks, a victory they wanted as a measuring stick for where they truly stood.

The game was physical, the win emotional and it all appeared to exact a toll on the Chiefs. They would go on to lose four of their next five games and not only fall from the AFC West championship race, but relinquish a playoff spot they appeared to secure when they locked up "Beast Mode" on fourth-and-1 in the fourth quarter.
