The only thing I feel sure of in the Seattle Seahawks defensive backfield, other than Contract Seekers Jamal Adams and Quandre Diggs as starting safeties, is that Marquise Blair and Ugo Amadi look really good. They’ll split the snaps at nickel safety, I mean, free corner, I mean, roverback. Watching Blair and Amadi materialize all over the field in Week 3 was a real treat, knowing that Adams and Diggs are ready to do the same when it counts. Positional flexibility is sexy, especially when it’s a defensive genius like Pete Carroll moving the chess pieces all over the board.
