The Seahawks' Chiefs Depth Chart suddenly looked a little different in Week 7, and this was the kind of change that matters more than it might first appear. Drew Lock was inactive because of an elbow injury, which meant Jalen Milroe moved into the backup quarterback role behind Sam Darnold for Sunday Night Football at Lumen Field.
That is not a minor administrative detail. It changes the shape of the game plan, the safety net behind the starter, and the level of comfort Seattle can have if something goes wrong. Lock had been listed as questionable on Friday, but once he was ruled out and dressed as the emergency third quarterback, the backup job fell to Milroe. In a prime-time matchup, that is the sort of depth chart adjustment that can quietly become a major storyline.
Seahawks inactives and what they mean
The Seahawks also went into Week 7 with Connor O'Toole listed as questionable on Friday, along with Nick Emmanwori, Uchenna Nwosu, and DeMarcus Lawrence. Tyrice Knight should figure to start similar to Week 6, which at least gives Seattle some continuity in a game where the margins are tight enough already.
But the quarterback situation is the headline here. Sam Darnold remains the starter, yet the backup picture shifted because Lock was unavailable. Jalen Milroe now sits one snap away from being forced into meaningful action, and that is exactly the sort of wrinkle that changes how a coaching staff thinks about protection, risk, and late-game decisions.
Kansas City’s notable absences
The Chiefs were also dealing with two notable absences of their own, with Jaylon Moore and Rashee Rice unavailable. So this was not a clean, fully stocked matchup for either side. Still, the Seahawks' adjusted quarterback depth chart is the sharper development because it directly alters the insurance policy behind Darnold.
That is the uncomfortable truth of roster management in the NFL: the depth chart only matters until the moment it suddenly matters a great deal. In Week 7, Seattle had to live with a different answer behind its starter, and that makes Drew Lock's inactivity one of the most important lineup notes of the night.
