The Seattle Seahawks' "Legion of Boom" is in a state of flux, and there is particular concern over the playing future of safety Kam Chancellor. After suffering a significant neck injury this past season, the former Pro Bowler's status for the 2018 season -- or any subsequent season, for that matter -- is an open question. But Seattle should have an up-or-down answer by this summer. Seahawks GM John Schneider said Chancellor will undergo tests in late June or early July in order to determine whether he will be able to keep playing football.
