Seattle Seahawks
As a tribute to the raucous fans that made the Kingdome the loudest stadium in the NFL the Seahawks retired the number 12 on December 15, 1984. Since then #12 Jerseys have been sold by the team and worn by Seahawk fans, often with the name “Fan” on the back. The Seahawks also have a ceremony before each home game where a flag bearing the #12 is raised by a prominent individual. In the 2005 season the fans were again making a difference in games and were recognized with the presentation of a special game ball for their efforts in a game against the New York Giants, a game in which the Giants committed 11 false start penalties in large part because of the crowd noise.
