Emanuel Wilson Runs for 100 Yards as the Seahawks Hand the Chiefs Their First Loss, and Patrick Mahomes' Slump Is Now a Lineup Question

The Seattle Seahawks handed the Kansas City Chiefs their first loss of the season on Sunday night, winning 20-3 at Lumen Field behind a defense that held Patrick Mahomes without a touchdown and limited former Seahawk Kenneth Walker III to 36 yards on 14 carries in his return to Seattle. Emanuel Wilson, filling in for the injured Zach Charbonnet, ran 24 times for 100 yards and a touchdown, and Jaxon Smith-Njigba caught nine passes for 150 yards and a score. Seattle improved to 4-3.

For fantasy managers, the game raised a question that would have sounded absurd in August: is Mahomes still a must-start quarterback?

How Seattle did it

Seattle's defense shut out the Chiefs in the first half and kept them out of the end zone for the full 60 minutes. Mahomes finished 19-of-33 for 165 yards with an interception. He was pressured 14 times and sacked once, and the protection issues were predictable: Kansas City played without right tackle Jaylon Moore, who was ruled out with a concussion before the game.

The Chiefs' receiver room was the other problem. Rashee Rice missed his third straight game with a hamstring strain, and with Tyquan Thornton on injured reserve after ankle surgery, the wide receivers combined for six catches and 39 yards, according to ESPN. That is not a group that can win when the running game also stalls.

On the other side, Sam Darnold threw for 257 yards and a touchdown, most of it to Smith-Njigba, and Wilson's 21-yard touchdown run late in the fourth quarter put the game away.

The fantasy lines

Here is who delivered and who did not on Sunday night.

The Mahomes problem

ESPN's fantasy recap logged Mahomes at a season-low six fantasy points and called him a non-must-start for now. The reasoning holds up. His supporting cast is thin until Rice returns, his line is banged up, and the offense has not produced explosive plays through the air.

Week 8 sends Kansas City to Denver on Nov. 1, a road divisional game that does not obviously cure what ailed the Chiefs on Sunday. Managers with a viable alternative, especially one in a high-total game, should consider it. Managers without one should start Mahomes and accept a lower floor than they are used to.

The key variable is Rice. If he practices fully this week, the outlook changes, because he gives Mahomes a reliable underneath option the current group lacks. If he misses a fourth game, Mahomes is a mid-range QB1 at best.

Walker's homecoming flop

Walker had scored multiple touchdowns in each of his previous two games, so a 36-yard dud was jarring. It was a bad matchup against a defense that knows him well and a game script that removed the run late. One game does not change his role: he remains Kansas City's lead back and a solid RB2. But the Chiefs' offense is not producing enough red-zone trips to make him the RB1 his early schedule suggested.

Emanuel Wilson and the Seattle backfield

Wilson's 24 carries were a true workhorse load, and he did something with them. The complication is Charbonnet, who was activated before the game but ruled out for Sunday. When Charbonnet is healthy, he is expected to reclaim a large share of the work, and Wilson becomes a change-of-pace option.

That makes Wilson a smart waiver claim this week but not a top-priority one. If Charbonnet is limited or out again for Week 8, Wilson is a strong flex in a Monday night home game against the Chicago Bears on Nov. 2. If Charbonnet returns at full speed, Wilson becomes a handcuff.

Smith-Njigba is a weekly WR1

There is no longer any debate here. Smith-Njigba is the focal point of Seattle's passing game, and a nine-catch, 150-yard night against a defense that had been unbeaten shows it holds up against good opponents. Start him every week.

The betting angle

Kansas City entered as a short road underdog in the market and lost by 17. Seattle's defense deserves the credit, but the more lasting takeaway for bettors is that a Chiefs offense without Rice and with a patched line does not look like the one that went unbeaten for six weeks. Kansas City's game totals may still be priced on reputation.

What to do in your league

Start: Smith-Njigba everywhere. Darnold is a streaming option in a home Monday night game.

Add: Wilson as a high-upside handcuff, with an eye on Charbonnet's practice reports.

Bench consideration: Mahomes, if you have a quarterback with a better Week 8 setup and Rice is not back.

Hold: Walker. One bad game against his former team is not a reason to sell.
