Winless preseasons cause for concern?

Wins and losses generally do not matter in the preseason. The summer is a time for evaluating rosters and putting together the right combination of players. But when a team goes winless in exhibition play -- and looks awful doing it -- it does catch your attention. It’s been a shaky preseason to say the least in the AFC East. The Miami Dolphins (0-4) capped their first winless preseason since 1989 with a 30-13 loss to the Dallas Cowboys on Wednesday.
