[If Carson Palmer can stay upright, the Cardinals will be much-proved on offense and that means more chances for Feely. He connected on 25-of-28 attempts in 2012 but Arizona's inability to score touchdowns only led to Feely making 25 extra points. There are better fantasy options out there but Feely should improve on the 100 points he scored last season.]
