However his supporting cast can improve, and with a better running game I think we will see teams attack the Bengals in a different way. The big thing is this, by the third yr you usually know what you have in a QB, by this time next yr I think we will know if the Bengals sign Dalton long term or look elsewhere for a QB.
With the rules changes the last few years, I don't know if a "game manager" can make it to the Super Bowl again, let alone win one. I wouldn't totally rule it out, but I think it is much more difficult to do it today than it was for any of the guys on the list in your first sentence (and Hasselbeck was a top 5 QB the year the Seahawks made the Super Bowl).
If you trust the NFL's version of advanced type of stats, Dalton has been a slightly below average QB his first two years. I think he has to improve to at least the level of above average (top 12 in the league) for the Bengals to be a true contender.
