7. Andy Dalton (Cincinnati Bengals, 2011)
Dalton was perhaps overshadowed a bit by Cam Newton, but you could argue that he was just as good, especially if you're into the "Quarterback Wins" statistic. Even without it, though, Dalton was formidable: 3,398 yards, with 20 TDs against just 13 INTs. And before the season, most people expected the Bengals to be just horrific. They exceeded all expectations and made the playoffs, due in large part to Dalton's steady play.
