They are mess and might battle the Cleveland Browns for title of league's worst team. They have several star players who are on the decline or disgruntled. Head coach Marvin Lewis must decide what do with quarterback Carson Palmer. The 31-year-old quarterback is threatening to retire if the Bengals don't trade him. The big problem with that proposition is teams can't trade players without a new CBA. So the Bengals are stuck in QB-limbo. If they draft a quarterback this April, it might diminish Palmer's trade value. Cincy has so many needs, it's going to be hard for the Bengals to turn it around. In all likelihood, this year will be Lewis' last as a Bengals head coach.
