The Seahawks bolstered their secondary in the first week of free agency, signing former 49ers cornerback Ahkello Witherspoon on Friday.
The addition of Witherspoon, a 2017 third-round pick out of Colorado, gives the Seahawks a starting-caliber option heading into 2021 with Shaquill Griffin agreeing to terms with Jacksonville in free agency, and with Quinton Dunbar currently an unrestricted free agent.
At 6-foot-3, 195 pounds, Witherspoon fits the mold of an outside corner in Seattle's defense, and there shouldn't be much of a learning curve given the similarities between the Seahawks defense and San Francisco's, which for the past four seasons was led by former Pete Carroll assistant Robert Saleh. Over four seasons, Witherspoon has started 33 of 47 games played, recording four interceptions, 24 passes defensed, 117 tackles, one forced fumble and one fumble recovery.
Witherspoon becomes the second 49ers defensive back added by the Seahawks in less than a year, joining D.J. Reed, who was claimed off waivers last summer, and who finished the season as Seattle's starting right cornerback after also starting games at left corner and nickel corner in addition to returning punts and occasional kickoffs. Depending on what happens with Dunbar and with competitions in camp—Tre Flowers will be in the mix for a starting job—Reed and Witherspoon could both be strong candidates for starting jobs.
