While the Seattle Seahawks had a decent run game against a bad rush defense, the god-awful secondary was the main culprit behind the Chiefs’ 31-38 road loss.

This game clinches a playoff spot for Seattle, but the Chiefs still have a chance to clinch the AFC West thanks to the Chargers’ loss to the Ravens on Saturday.

Late in the game, Russell Wilson, Seahawks quarterback, made several deep passes that were either caught or, more commonly, were called for pass interference on Kansas City.

The Kansas City secondary was without Ron Parker, Chiefs safety, Kendall Fuller and Orlando Scandrick, Chiefs cornerbacks, on Sunday. Fuller was declared inactive after undergoing surgery and Scandrick was cast aside for Tremon Smith, rookie cornerback, to start. Charvarius Ward, rookie cornerback, also got a good share of playing time against the Seahawks.

Throughout Sunday night at Seattle, the rush offense gave the Chiefs some trouble. Chris Carson, Seahawks running back, ran for 116 yards and two touchdowns on 27 carries. Wilson managed to tally 57 rushing yards on eight attempts and got several first downs after scrambling beyond the line of scrimmage.

In addition to the awful defense throughout the entire game, the first half was awful for Kansas City’s offense. They only scored one touchdown and one field goal but lost two fumbles from Damien Williams, Chiefs running back, and Chris Conley, Chiefs wide receiver.

In the first quarter, Patrick Mahomes, Chiefs quarterback, only completed two of his eight passes.

Mahomes finished the game with 273 passing yards and three passing touchdowns while completing 23 of his 40 passes. He also ran for 33 yards and completed a two-point conversion.

Williams continued to start in place of the injured Spencer Ware, Chiefs running back. He ran for 103 yards on 13 carries.

Tyreek Hill, Chiefs wide receiver, received for 74 yards. Conley and Travis Kelce, Chiefs tight end, received for 54 yards each. Charcandrick West, Chiefs running back; Williams and Demarcus Robinson, Chiefs wide receiver, each received one touchdown.
