Cornerback Rock Ya-Sin has signed with the Detroit Lions after spending the previous season with the San Francisco 49ers. Ya-Sin played in 13 games for the 49ers but did not start any, primarily contributing to their struggling special-teams unit. His departure follows the exit of several veterans signed last offseason, including Leonard Floyd, Maliek Collins, and De’Vondre Campbell. These players were brought in under the 49ers’ former defensive coordinator Nick Sorensen and assistant head coach Brandon Staley, but with those coaches now replaced by Robert Saleh and Gus Bradley, the team is moving in a different direction. The 49ers are focusing on filling their roster with cost-effective rookies this season, and it’s expected they will draft a cornerback to compete for the No. 3 spot behind Deommodore Lenoir and Renardo Green.
