Walker has signed his rookie contract, John Boyle of the Seahawks' official site reports.
The same applies to fellow 2022 second-round pick Boye Mafe and fourth-rounder Coby Bryant, meaning that Seattle's entire nine-player draft class is now under contract. With Chris Carson planning to retire from the NFL because of a neck injury, Rashaad Penny and Walker top the Seahawks' running back depth chart, with Michael-Shawn Dugar of The Athletic noting that the duo are in line to work as the team's primary early-down options. DeeJay Dallas and Travis Homer are expected to share third-down duties. Though Walker has plenty of long-term upside, it may take him some time to become a steady fantasy producer, with ESPN's Brady Henderson indicating that Penny (who led the NFL in rushing over the final five weeks of last season) projects as Seattle's primary running back to begin the coming season.
