Seemingly every year, the Seattle Seahawks bring in a veteran defensive tackle and receive solid production from what was an unheralded signing. Ahtyba Rubin started 32 games in two seasons after arriving with little fanfare; Kevin Williams was signed in the middle of June, then started in Super Bowl XLIX the following February.
After losing Sheldon Richardson to the Minnesota Vikings in free agency, Seattle signed not one, but two of the Vikings’ DTs. Shamar Stephen and veteran Tom Johnson were brought in to fill similarly unheralded, but important roles.
