Seattle Seahawks
Dating back to the ‘Legion of Boom’ days, the Seattle Seahawks have boasted one of the best home-field advantages in the NFL. Due to their effect on the game, fans in Seattle have nicknamed themselves the ’12th man’.
As a matter of fact, the No. 12 jersey has become a popular number for fans to wear while attending games. Despite falling short of a Super Bowl in recent years, the Seahawks have continued to have some of the most supportive fans in the league.
Over the past decade or so, the Seahawks have typically fared better when playing at CenturyLink Field. However, Seattle would be unable to have that luxury if NFL games end up being played without fans.
