Catcher had 9 Qualifying players in 2011 (Obviously there were many catchers close, but only 9 qualified)
*Also take into account that Mauer and Posey were injured most of the year
*Some Catchers (Carlos Santana) had more plate appearances due to playing another position

Some more defensive notes:
Wieters ranked 1st in the entire league with 14 DRS (Total Defensive Runs Saved)
He also ranked 1st with 5 RSB (Stolen Based Runs Saved)
Overall, I would say that Wieters was very satisfying from a Catchers standpoint last season. The defense was top tier, and the hitting aspect of his game is only going to get better.
One final fun note:
Bill James projection on Wieters in 2012: .281AVG/.353OBP/.468SLG/.304BABIP/.357wOBA
I would gladly take that!
