When former Legion of Boom member Richard Sherman was released by the Seattle Seahawks and immediately signed with the rival San Francisco 49ers a lot of fans were upset that the Hawks had passed up an opportunity to match what was viewed as a deal that was potentially extremely team-friendly. Now, more than six months later, with All World safety Earl Thomas on injured reserve, the Seahawks current starting secondary has a combined 2018 cap hit that is lower than Sherman's cap hit, even with his deal as team friendly as it may be.
Even if Sherman were to not play another down in 2018, he would end the season with a cap hit of $5.625M ($1M pro rated portion of his $3M signing bonus, $2M in base salary, $2M roster bonus for having passed his physical and making the 53 man roster and $625k in per game roster bonuses for the five games in which he has already appeared).
Meanwhile, the current starting secondary, comprised of cornerbacks Shaquill Griffin and Tre Flowers with the safety spots manned by Tedric Thompson and Bradley McDougald, has combined cap hits of $5.39M, with McDougald accounting for more than sixty percent of that amount.
Obviously the team has a significant amount of money tied up in the secondary that is not performing on the field right now. That includes injured reserve money for Kam Chancellor and Earl Thomas, along with the dead money from the contracts of former Legion of Boom members Jeremy Lane and Richard Sherman. However, the fact that the team currently has a young and inexpensive secondary should help as the team looks to extend key members over the coming year, such as Frank Clark, Jarran Reed and Germain Ifedi just to name a few.
