No. 4 - Safety Quandre Diggs
As bad as Jamal Adams has been in 2023, Quandre Diggs has arguably been worse. In a way, this is a bit sadder. The reason I say this is because many times since Diggs was traded to Seattle during the 2019 season, he has saved bad coverage by flying around the back end of the secondary. In 55 games for Seattle between 2019 and 2022, Diggs had 17 interceptions and 27 passes defended.
But in 13 games in 2023, Diggs has just 1 interception and 3 passes defended. His passer rating allowed is a career-high 100.2 this season. He has allowed 10.5 yards per target which is his second-highest amount since 2018. He is also missing 12.0 percent of his tackles, his highest number since 2019.
I would also like to believe that the leg injury that Diggs suffered late in the 2021 season is somehow affecting him, but this would be false. He was fine last year and played every game so there was no reason his injury would skip a year of slowing him down. While Jamal Adams is the number 75 graded safety, per PFF, Adams is 85 - seventh-worst in the league.
Diggs is a free agent after 2024, but next year he has a cap hit of $21,262,500. His dead cap is $10,262,500 meaning Seattle would save $11 million by moving on from Diggs. That would seem like a no-brainer at this point.
