The Seahawks weren't at their best on Sunday, particularly on offense against a very good 49ers defense, but they were able to do enough to mount a fourth-quarter comeback that featured two impressive touchdown drives to erase a two-score deficit. The end result was a 26-23 victory over the 49ers that improved Seattle's record to 12-4, though the win wasn't enough to improve Seattle's playoff seeding. 

More on that, and other rapid reactions from Seattle's Week 17 win over the 49ers:

1. The Seahawks improved to 12-4, but remain the No. 3 seed.

The Seahawks had a chance to improve their playoff seeding with a win, but only if they got some help from the Bears and/or Panthers, who played Green Bay and New Orleans. The Packers and Saints both won, however, meaning Green Bay is the No. 1 seed and gets a bye, while New Orleans is the No. 2 seed.

As the No. 3 seed, the Seahawks will host the Los Angeles Rams, who beat the Cardinals to secure the No. 6 seed. It will be the second meeting between those teams at Lumen Field in three weeks, with the Seahawks beating the Rams 20-9 last weekend.

2. Can you win the game in the fourth quarter?

For the Seahawks, the answer was an emphatic yes on an afternoon where, through three quarters, it was a struggle for the offense.

Seattle's defense, which has been outstanding for the past two months, was dominant early, but the 49ers got going in second and third quarters and were able to take a 16-6 lead early in the fourth quarter.

But as he has done so often in his stellar career, Russell Wilson was able to get going when the Seahawks needed it most, and after the Seahawks offense managed just 3 yards in the third quarter on a pair of three-and-out drives, they started the fourth quarter by going 75 yards on 8 plays for drive that ended on a Tyler Lockett touchdown grab.

After Seattle's defense got a stop, Wilson and company went 85 yards, with Wilson again finding Lockett for the score, this time on fourth-and-goal. On those two touchdown drives, Wilson completed 8 of 12 passes for 74 yards and two scores, and also scrambled twice for 27 yards.

Any hopes the 49ers had of a comeback of their own went away when Benson Mayowa sacked C.J. Bethard and forced a fumble, setting up an Alex Collins touchdown run. That Collins touchdown and the ensuing extra point gave the Seahawks 459 points for the season, a new franchise record, beating the 452 points scored by the 2005 team.

3. A special receiving duo.

On the same drive early in the second quarter, Tyler Lockett and DK Metcalf made Seahawks history both individually and as a duo, cementing themselves as the most productive receiving duo in team history.

With a pair of short catches, Metcalf broke Steve Largent's 35-year-old franchise record for receiving yards in a season. A few plays later, Lockett recorded his 95th reception of the season, breaking the franchise record previously shared by Doug Baldwin and Bobby Engram.

On that same drive, Lockett went over 1,000 yards for the second straight season, making him just the sixth Seahawk to accomplish that along with Largent, Baldwin, Brian Blades, Joey Galloway and Darrell Jackson.

Lockett going over 1,000 yards also made Lockett and Metcalf just the second Seahawks duo in franchise history to record 1,000-yard season in the same year, joining Blades and Galloway, who did it in 1995.

Metcalf, who earlier this month was named a Pro-Bowler for the first time, finishes his regular season with 83 catches for 1,303 yards, while Lockett finished with 100 catches for 1,054 and 10 touchdowns.

4. Lockett likes playing in Arizona.

Thanks to the 49ers having to finish their season in Arizona, the result of COVID-19 restrictions in Santa Clara county, the Seahawks played two road games at State Farm Stadium this season. And one player who apparently didn't mind an extra game in Glendale was Lockett.

Lockett, who in Week 7 had 15 catches for 200 yards and three touchdowns against the Cardinals, added 12 catches for 90 yards and two scores on Sunday, meaning in two games at State Farm Stadium, he had 27 catches for 290 yards and five touchdowns.

5. Benson Mayowa was a great offseason pickup.

While the trades for Jamal Adams and Carlos Dunlap II have rightly gotten a lot of attention this year, another 2020 acquisition that has paid dividends was the offseason signing of veteran pass-rusher Benson Mayowa.

Mayowa has been good all season for the Seahawks, and he saved one of his best performances for Sunday, recording a pair of sacks, the second of which forced a fumble that was recovered by Rasheem Green, giving the Seahawks the ball in the red zone, a turnover they'd turn into an Alex Collins touchdown that put the game out of reach.
