Saturday the Seattle Seahawks dropped the preseason opener 20-7 to the Las Vegas Raiders with none of the projected starters on the offensive side of the ball seeing the field. All the big names, from Russell Wilson to his skill position players and the entire starting offensive line were rested with nothing meaningful on the line. That gave the younger players competing for a spot on the roster the opportunity to show what they can do, and one battle that will be fascinating to watch over the coming weeks is the four man competition for the swing tackle role.
