The preseason is about exposing and correcting flaws. Coaches are worried. That's just what they do. They look at their team and see the problems because every team has them. After one full preseason week, here's what we'd be concerned about for all 32 teams.
Arizona Cardinals: No matter what they say, Cardinals brass would prefer Kevin Kolb take the quarterback job. They are paying him huge money and gave up draft picks for him. But Kolb only seems to be regressing. The discouraging thing here is that new favoriteJohn Skelton hasn't looked particularly good either in practices or in preseason games.
Miami Dolphins:Cutting Chad Johnson was the right move. But it's hard to see any quarterback having a lot of success with the supporting cast in place in Miami.
