NFL record for most touchdown passes through the first three games of the season. The Seahawks defense continued to give up a lot of passing yards, allowing 397 and 472 in those two games, respectively. A win over the Miami Dolphins followed by a comeback victory over the Minnesota Vikings marked the first 5–0 start in franchise history. The Seahawks suffered their first loss of the season at the hands of the Arizona Cardinals, which ended with a Zane Gonzalez field goal in the waning seconds of overtime. The Seahawks bounced back with a 37–27 victory over their division rivals, the San Francisco 49ers, with their defense allowing just 117 yards and one touchdown through the first three quarters of play. However, any progress made by the Seahawks defense was erased the following week against the Buffalo Bills, as they allowed 415 yards, an 81.6% completion percentage, and 4 total touchdowns to quarterback Josh Allen as the Seahawks suffered their second loss in three weeks, having given up 44 points, the most since Pete Carroll took over as head coach. They suffered their third loss in four outings against the Los Angeles Rams. On November 19, 2020, the Seahawks announced that CenturyLink Field was renamed to Lumen Field due to CenturyLink rebranding as Lumen Technologies starting on their Thursday night rematch with the Cardinals. They won the game 28–21, with their defense turning a corner, holding the Cardinals' top-ranked offense to 314 yards, compared to 519 in their last meeting. Dunlap had 2 sacks and three quarterback hits, including the game winning sack on fourth down with under a minute to play. The defensive momentum continued into the next matchup with the Philadelphia Eagles, where the defense had 6 sacks, an interception, and didn't allow a first down until the Eagles' 6th drive. They also allowed 250 total yards and 17 points, both season bests. Their offense was shut down by the New York Giants as they were upset 17–12, but they bounced back against the then-winless New York Jets 40–3. After a narrow 20–15 win over the Washington Football Team, the Seahawks' defense dominated the Rams, beating them 20–9 and clinching the NFC West for the first time since 2016. They rounded out the season with a 26–23 win over the 49ers. The Seahawks achieved a record of 12–4 for just the third time in team history, as well
