Every Friday from right about now until at least the first month of 2016 (but hopefully all the way until Super Bowl 50) you’ll see them: Seemingly every other person on the street, on your bus, in the office dons a Seahawks jersey. Two days before game day the city’s collective fever for its Super Bowl–winning NFL team turns a fiery cobalt—everyone sheathes themselves in the navy blue nylon and spandex mesh shirts emblazoned with No. 25 (Richard Sherman), No. 24 (Marshawn Lynch), No. 3 (Russell Wilson), or No. 12 (signifying the Hawks fan base, the 12th Man). Governor Jay Inslee even made it official, days before a playoff game that helped send the team to the first of two consecutive Super Bowls, when he signed a gubernatorial proclamation that decreed January 10, 2014, Seahawks Blue Friday.
