Last week, we took a look at each possible playoff opponent for the Seattle Seahawks in the second round of the NFL playoffs. It looked like a lock that the Green Bay Packers would be headed to Lumen Field before they inexplicably choked away a 21-3 lead against the Chicago Bears, losing 31-27. Then, San Francisco pulled off the upset against the defending Super Bowl champion Philadelphia Eagles on Sunday, setting up a third game between the NFC West rivals, just two weeks after their second meeting. Seattle controlled that January third matchup throughout, leaving Santa Clara with a 13-3 victory. Let's take a look at what the Seahawks need to do to repeat that performance.

Offensively: Repeat success on the ground

One of the reasons Seattle won so handily in Week 18 was their significant time of possession advantage, 37:48-22:12. They were able to achieve this because of their success on the ground, rushing 39 times for 180 yards. Both Kenneth Walker and Zach Charbonnet rotated in seamlessly, with Walker taking 16 carries and Charbonnet 17.

The Niners' run defense has been good this season and is coming off a game against Philly in which they held Saquon Barkley in check. Barkley’s 106 yards on 26 carries look solid on paper, but after his first two touches went for 31 yards, his next 24 yielded just 75, a rough 3.1 yards per carry. While that performance is likely to inject some confidence into the San Francisco front seven, it was actually one of Barkley's best games of the season, going over 100 yards for just the fourth time this season, and showcasing how far the Eagles' rushing attack has fallen in 11 months.

All that being said, Seattle should be able to have success on the ground as long as Klint Kubiak stays patient with it and hammers the interior of the 49ers' defensive line, where Kalia Davis, CJ West, and Alfred Collins have all posted nightmarish PFF grades defending the run.

Defensively: Continue to send pressure from everywhere

Seattle was afforded the benefit of playing San Francisco without their all-pro tackle, Trent Williams, and his absence was felt from the jump. Backup Austin Pleasants was miserable, surrendering three pressures and posting a 39.6 pass blocking grade. Going from Pleasants back to Williams likely neutralizes some of the relentless pressure that Seattle put on Brock Purdy, but the rest of the offensive line wasn’t much better.

Center Jake Brendel gave up three pressures of his own, while right tackle Colton McKivitz and left guard Spencer Burford allowed four each, so the line is still extremely vulnerable to Seattle's pass rush, especially if they continue to send second-level pressures. Seattle sent safety Nick Emanwori as a blitzer five times in week 18, and he registered two pressures, while also sending Drake Thomas, Ernest Jones, and even Ty Okada throughout the game. Seattle should actually blitz more often in this game, as the Niners lost George Kittle to an Achilles injury against the Eagles, leaving San Francisco with Jauan Jennings and Ricky Pearsall (status unknown) as their only reliable winners against single coverage.

Finally: Keep Faith in Jason Myers

To put it nicely, Jason Myers' game against San Francisco was rough, going two-for-four on field goal attempts with an inexplicable miss from 26 yards away.

It shouldn’t take away from the season Myers has had, though. 41/48 on field goal attempts, including his 6/6 performance that accounted for all of Seattle's points against the Colts in week 15. That 26-yard miss was also just the second time in his career that he’s put one wide from inside of 30 yards, with the first coming all the way back in 2015. If Seattle is going to try and win this game the same way they did in Week 18, defense and time of possession, it will probably serve them better take points when available rather than turn the ball over on downs and risk giving a struggling offense some life.
