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 favorite John Skelton hasn't looked particularly good either in practices or in preseason games.
Atlanta Falcons: Last year's middle linebacker Curtis Lofton is making a big impact in New Orleans. Meanwhile, Lofa Tatupu is out for the year and expected starting MLB Akeem Dent suffered a concussion in the preseason opener.
Buffalo Bills: By all accounts, backup quarterbacks Tyler Thigpen and Vince Young have both struggled throughout camp. The offense from top to bottom was manhandled by the Redskins in the preseason opener.
Chicago Bears: Offensive coordinator Mike Tice is already resorting to motivational tactics because he's not happy with left tackle J'Marcus Webb. Meanwhile, no one seems to know when Brian Urlacher will be healthy again.
Cincinnati Bengals: The team's banged-up secondary is now joined by a banged-up rest of the team. Starting guard Travelle Wharton is out for the year, while defensive end Carlos Dunlap is out a month.
Detroit Lions: It's now mid-August and we still don't know anything more about when running back Jahvid Best will return to the field from his concussion problems. Second year-pro running back Mikel Leshoure has been hurt all camp. They are relying on Kevin Smith way too much.
Jacksonville Jaguars: Blaine Gabbert enjoyed one strong drive and a few ugly plays after that in his preseason opener. We'd be a little worried (but not surprised) that Laurent Robinson may be overmatched as a "No. 1" receiver.
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.
New England Patriots: There are more questions on the offensive line than when camp started. Guard Brian Waters is nowhere to be found, Robert Gallery retired and tackle Sebastian Vollmer is hurt. Players take on different roles daily.
New York Giants: New York's defensive line isn't nearly as deep as you think. The top-heavy group has been hit by injuries to the non-stars. With cornerback Terrell Thomas hurt, former first-round pick Prince Amukamara also needs to step up after struggling in the preseason opener.
Pittsburgh Steelers: The Steelers can survive until Mike Wallace returns. They can't survive left tackle play like they got from rookie Mike Adams in his debut. The rest of the line doesn't look great either. Sound familiar?
San Diego Chargers: The Chargers are counting so much on running back Ryan Mathews. When he returns from his broken collarbone, how can they be confident he's going to be the 350-touch guy they expect?
Seattle Seahawks: The wide receiver situation is more confusing after a few weeks than it was when the Seahawks started camp. Matt Flynn looks like the presumptive starter at quarterback, but who will start with him in Week 1? It would be great to see Sidney Rice in a preseason game.
Tennessee Titans: Kenny Britt hasn't been suspended yet. He also hasn't practiced, which is no surprise coming off his third surgery since last season. Chris Johnson also had a disappointing preseason debut with a pair of drops and negative plays.@greggrosenthal.
