FIP. Fielding Independent. Really?

Fielding Independent Pitching (FIP) measures what a player’s ERA should have looked like over a given time period, assuming that performance on balls in play and timing were league average. Fangraphs relies on FIP to calculate WAR for pitchers.
Is FIP independent of the catcher?
The following table shows pitching performance by catcher over the last two seasons.
Catcher Inn K/BB FIP Joe Mauer 1286 2.32 4.32 Ryan Doumit 865 1.65 4.78 Drew Butera 307 2.53 3.80 Chris Herrmann 228 2.18 4.44
Could this be random variation? Sample size? The number of innings for the catchers exceeds that expected of a starter in a full season.
Is it possible that Butera always caught the more talented pitchers? The Twins haven't had a starter really stand out to make this difference.
As the Twins make roster decisions for next year, can they move forward with any plan to play Doumit at catcher? Even if the difference between Butera and Doumit was half the the difference in FIPs, there is no way Doumit made up for that difference with the bat.
Successful teams are playing catchers that can't hit.
Drew Butera returns a real prospect in trade.
The Twins need to start paying attention.
