Supporters this year introduced the innovative 'Seahawk wave' -- a noisy, human wave that rolled round and round the Kingdome stands as fans stood and cheered in section-by-section synchronization.'That's basically a self-imposed trademark of the fans to make noise while the other team has the ball,' explained one fan. 'It started as a ruse by University of Washington Huskies fans.'
