The biggest loss, however, came at quarterback, as Jayden Daniels was carted off the field in the fourth quarter with an arm injury. He walked back to the locker room with a cast on his left arm.
The Seahawks, now 4-0 on the road, had success in nearly every metric against the Commanders, who dropped their fourth consecutive loss to move to 3-6. They doubled the Commanders in total yardage in the first half, 330-140, and were perfect on their first five third-down attempts. They averaged 12.2 yards per play in the first half, compared to the 5.5 from Washington's unit, and turned two Washington turnovers into touchdowns.
Darnold finished the night 21-of-24 for 330 yards with four touchdowns, one interception and a 141 passer rating.
But in several ways, the Commanders' mistakes were just as much to blame as a historically productive night from the Seattle offense. The two turnovers -- an interception from Jayden Daniels and a fumble from Jaylin Lane on a kickoff return -- were the most glaring gaffes, but an amalgamation of penalties, missed tackles and communication issues also stifled any attempts from the Commanders to climb back into the game.
It started on the Commanders' opening drive of the game. An illegal blindside block moved the unit back 15 yards, eliminating most of the progress the Commanders made on the previous four plays. The Commanders were forced to punt after an eight-yard completion to Zach Ertz on third-and-21.
The Seahawks set up shop at their own 10-yard line and marched down the field on a 12-play scoring drive -- their first of five in the first half. The Seahawks completed a first-and-25 with completions to Jaxon Smith-Njigba for 13 and 14 yards as well as an eight-yard reception from tight end A.J. Barner. Later in the drive, a pass interference call on Marshon Lattimore moved the ball to the Commanders' 3-yard line, and Tory Horton finished things off with his first touchdown catch of the night.
The Commanders put together a solid response on their ensuing drive, moving to the Seahawks' 40-yard line following a nine-yard gain from Deebo Samuel. But a facemask penalty negated a six-yard run from Daniels on third-and-2, moving the Commanders back for a third-and-17. Daniels threw an interception on the next play, and the Seahawks moved 60 yards downfield to go up 14-0 with a 25-yard catch from Horton on a third-and-8.
