Seattle Seahawks Super Bowl-winning coach Pete Carroll has joined the 19th Man.

A member of Seattle’s ‘12th Man’, Carroll showed off his new Adelaide with the No.19 in a tweet on Wednesday. The jumper was given to the respected NFL coach by the Adelaide Football Club as part of the developing relationship between the Seahawks and Crows.

Earlier this year, Seahawks head trainer David Stricklin visited West Lakes, spending time with Crows head trainer Vinnie Del Bono and taking in his first AFL game. This followed Del Bono’s trip to Seattle, where he spent a day with the Seahawks, in 2012.

Regarded as the loudest fans in the NFL, the 12th Man give Seattle a home field advantage. On December 2, 2013, Seahawks fans registered a decibel reading of 137.6, a Guinness Book World Record.
