SEATTLE – Matthew Stafford admitted postgame that he didn’t know in advance that he would throw the ball on arguably the most important play of Sunday’s game.

“But sometimes these things happen,” the Rams quarterback said. “You come out clean and D-Rob does a great job of winning at that point, then stalling him and then catching him.”

This clean sheet resulted in the game-winning, walk-off touchdown — a 39-yard pass to wide receiver Demarcus Robinson — that lifted the Rams to a 26-20 victory over the Seahawks.

Wide receiver Cooper Kupp said the goal of the play was to be able to “clear the advantage for Matthew” and “give him a chance to make a play and do something sweet.” It was Kupp closing the edge that allowed Stafford to shoot at Robinson.

“After I saw him, I made myself available,” Kupp said. “That ball is very rarely thrown that way. D-Rob did a great job off the line of scrimmage, and when he put that angle up, I couldn’t believe it when I saw Matthew turn his hips. I was like, ‘Oh, he’s about to let this go.'”

Robinson’s one-handed catch at the end was just as impressive as the pass, though he wasn’t doing it for style points.

“I was just trying to keep the guy out because he (Seahawks cornerback Riq Woolen) was kind of catching up to him,” Robinson said. “Woolen was pretty fast, so he was catching up to the ball. Because, you know, it takes a while for the ball to get to me. So he was catching up. So I said, ‘Okay, let me stay. My arm’s out,’ he said, and he started grabbing my arm, so he was trying to make a play.” “I only had one arm.”

“You know, when I threw D-Rob’s body language, I was like ‘oh no, I threw it under’, I thought I might have thrown a plate at his body language,” Stafford said. “He did a great job keeping it at bay.”

It was a fitting end to a game-winning drive that began with a pair of explosive completions from Stafford: an impressive 24-yarder to wide receiver Tyler Johnson, followed by a 16-yarder to wide receiver Tutu Atwell. Stafford said Johnson did a good job of getting ahead of Woolen and that he “had no choice” on this shot; The timing of this throw narrowly avoided a tackle from an incoming Seahawks defender. Stafford also praised Atwell for a great job breaking away from his defender on that deep comeback route.

It was also a rewarding finish for the Los Angeles defense.^This-down, redzone stop in overtime, initiated this move after having to make up for some of the hardships the offense endured in the first half and parts of the second half.

“It’s our turn, man,” Robinson said of the offense’s mentality as he took the ball in overtime after the defender. “The defense did a great job stopping us and giving the ball back. It was our turn to put points on the board. We had to either get three points and finish the game, or not leave it to the kicker. We were trying to score a goal to get this over with.”
