why are seahawks fans 12

Seahawks fans are called “12s” because the team considers them the 12th player on the field, an extra force beyond the 11 players allowed in the game at any one time.

Quick Scoop: Why “12”?

  • In American football, only 11 players from one team can be on the field at a time, so the loud home crowd is treated as the “12th player.”
  • The Seahawks honored this idea on December 15, 1984, when they retired jersey No. 12 specifically for their fans, something no player can wear now.
  • Since then, “12s” has become the official nickname for Seahawks fans, showing that their noise and energy are part of the game plan, especially at Lumen Field.

A Bit of History

  • The fan nickname started as “12th Man,” echoing the idea that the fans act like another player on the field.
  • Texas A&M had already used and trademarked “12th Man” (going back to 1922), so the Seahawks reached a licensing deal to use the phrase.
  • When that agreement expired around 2016, Seattle shifted away from “12th Man” and leaned fully into the shorter, cleaner “12s.”

Traditions That Made “12” Stick

  • The Seahawks retired the No. 12 jersey in 1984 purely for the fans, making it a permanent symbol of the crowd’s importance.
  • Before every home game, a special guest (often a former player, local hero, or celebrity) raises the giant “12” flag, officially “waking up” the crowd.
  • Around Seattle, 12 flags fly from buildings, houses, and businesses, especially in the playoffs or before big games.

Why It Matters Today

  • The 12s are known for being extremely loud; their noise has been linked to opponent false starts and communication breakdowns, and even helped inspire NFL discussion of crowd noise rules.
  • Lumen Field was engineered to trap and reflect noise back toward the field, amplifying the presence of the 12s and making home games notoriously tough for visiting teams.
  • Over time, “being a 12” has come to mean a full identity—loyalty to the Seahawks, community events, fan charities, and a reputation as one of the NFL’s most intense fan bases.

TL;DR: Seahawks fans are “12” because the team retired jersey No. 12 for them and treats their crowd noise as a literal extra player—the 12th—on game day.
