Christian Ponder more comfortable in offense

Vikings OC Bill Musgrave says QB Christian Ponder is much more comfortable in the offense this year than he was last.  That's not surprising considering Ponder was a rookie with a shortened offseason last year.  But it's still nice to hear that he's made the expected Year 2 jump.  Ponder posted mediocre numbers in 2011, but we liked his arm strength and mobility.  With RB Adrian Peterson coming off a torn ACL, the Vikings figure to put the ball in the air more often this season.  That could make Ponder a sneaky QB2 option.
