Zorn, Campbell Seeking A More Perfect Union

There is a voice in Jason Campbell's head, and depending on the point he is at in his Sunday, it can be high-pitched and hyper, soothing and calm, reassuring or ranting. ' Are you sure ? Are you sure? ARE YOU SURE?' 'Some of that stuff I might say . . . it's just idle chatter,' Jim Zorn said. But it is, as Zorn put it, 'nervousness' only occasionally. Mostly, it is substantive discussion. Campbell and Zorn, the quarterback and coach of the Washington Redskins, will be linked Sunday by the wireless microphone that allows Zorn to speak directly into Campbell's helmet when the Redskins face the Detroit Lions, losers of 19 straight games, at Ford Field.
