Andy Dalton, Cincinnati Bengals: The Bengals are good enough to win even when Dalton plays terrible for a half. His accuracy always has been streaky, which is a bad combination with a lack of arm strength. It appears Dalton came into the NFL fully formed and hasn't developed much since his rookie season. His defense and weapons are excellent, so Dalton very well might be a "winning quarterback." But the Bengals have to wonder if they could do better if Dalton doesn't progress.
