What happened: The two-time Pro Bowler joins Seattle ahead of the 2026 season. He will compete for a role in a secondary dealing with injuries.
Why it matters: The move gives Seattle an experienced cornerback during the preseason. Diggs gets a short-term opportunity to reestablish himself after leaving Dallas.
By the numbers: Diggs, 27, has 20 career interceptions and 63 passes defensed.
What to watch: His preseason workload and place in Seattle's cornerback rotation bear watching.
