FILE - In this Sept. 13, 2015, file photo, Seattle Seahawks head coach Pete Carroll yells on the sideline during the fourth quarter of an NFL football game against the St. Louis Rams in St. Louis. Carroll hit his stride at USC, and NCAA investigators were hot on his trail when he lit out for a third NFL audition in Seattle. Two Super Bowl appearances and one trophy later, he's practically a fixture in the Pacific Northwest. (AP Photo/Tom Gannam, File)
