The Seattle Seahawks concluded their disappointing 2021 campaign with a two-game winning streak, capped by an impressive 38-30 win over the Arizona Cardinals in Week 18. Russell Wilson and his squad successfully weathered the Cardinals' comeback bid in order to escape the desert with a season-ending dub, so it's time to look at some Week 18 takeaways for the Seahawks.

With the victory, Pete Carroll's squad finished the regular season with a 7-10 record for the fourth spot in the NFC West. They also denied the Cardinals of the divisional title, which went to the Los Angeles Rams after their loss in this matchup. Certainly enough, the Seahawks aren't used to ending their season this early, and there will be some big decisions to make moving forward.

But for now, Week 18 takeaways for the Seattle Seahawks.

Seattle Seahawks Week 18 Takeaways

3. Tyler Lockett torched the Cardinals again

Last season, the Seahawks had an eventful game in Week 7 against the Cardinals, as the two divisional rivals went head-to-head in a tightly contested game. Seahawks wide receiver Tyler Lockett was the man of the show career-high numbers of 200 receiving yards on 15 catches and three touchdowns.

Lockett played well in the first game against Arizona this season, and then he made sure that he would remain at the forefront of Seattle's offensive attack once again in Week 18. Lockett put up a big performance on Sunday with 98 receiving yards on five receptions to go with two touchdowns for the Seahawks.

The former Pro Bowler's impressive outing enabled Seattle to put up points across the board to eventually overcome Arizona. Lockett also finished their 2021 campaign with a new career high in total receiving yards in a season.

2. Rashaad Penny was a monster on the ground

Running back Rashaad Penny was on fire for the last couple of weeks of the season. In last week's game against the Detroit Lions, he put up 170 rushing yards on 25 carries and two scores in a blowout win.

He carried over his rhythm in Week 18, exploding for a career-high 190 rushing yards on 23 attempts and a TD against the Cardinals. The 25-year-old was also responsible for a 62-yard touchdown run that iced the game for his team.

Penny surely made a strong impression to cap the 2021 season as he is expected to enter free agency after the team declined the fifth-year option on his contract. Amidst the uncertainty of his future in Seattle, the young running back was able to do his part as he proved that he is capable of being a reliable rusher and is deserving of a new contract, be it with the Seahawks or another team.

1. Russell Wilson is here to stay, at least for now

Prior to the 2021 season, there was a reported rift between Russell Wilson and the Seahawks regarding his future with the team as he sought more help to protect him in the pocket. Many rumors swirled around the eight-time Pro Bowler, but he still found himself playing for Seattle throughout the duration of the campaign.

In Week 18 against the Cardinals, Wilson had a solid performance with 238 passing yards on 15-of-26 passing and three touchdowns and a scoring run. Yes, it wasn't a perfect game for Wilson, especially as he committed a forced fumble and an interception, but he was able to do just enough to lift his team to a resounding victory.

Recently, Wilson claimed that he wants to win more Super Bowls in Seattle, and the latest rumors coming from the team suggest they don't want to trade him. For now, it seems like both sides are on the same page and are looking to put the past behind them to move forward together. Hopefully, the resolution of the issue will allow the Seahawks to get back on their feet and return to their old playing form next season, but things can still change and Wilson's future will be something to keep an eye on.
