Actually, the point was the comparison to Posey with other catchers, who typically suffer far more day-to-day wear and tear on the body. 

Posey was a catcher roughly 75% of the time (76% to be more precise), based on ABs.  The rhetorical question is does that same percentageapply to the other catchers you compared him to?  I suspect not (but don't know).

Fair enough. Top five catchers in MLB ranked by Runs Created (minimum 300 plate appearances):

1. Buster Posey (89.9 RC) - 400 PA as a catcher, 163 PA as a IB/DH/PH
2. Gary Sanchez (84.1 RC) - 442 PA as a catcher, 79 PA as a 1B/DH/PH
3. J.T. Realmuto (77.8 RC - 528 PA as a catcher, 48 PA as a IB/DH/PH
4. Yadier Molina (66.6 RC) - 529 AB as a catcher, 4 AB as a IB/PH
5. Mike Zunino (63.8 RC) - 429 PA as a catcher, 6 PA as a DH/PH

Your point is valid that Posey benefits to some extent (although difficult to quantify) by moonlighting as a first baseman, however note that even the 10th ranked primary catcher in MLB (Alex Avila) only recorded a 53.9 RC (with 295 PA as a catcher and 86 PA as a IB/DH/PH).

His OPS when catching was .863 while his OPS as a 1B/DH/PH was .854, so while Posey benefited from less wear and tear over the course of the season his performance was consistent regardless of where he played.

The bottom line is that Posey is an extremely valuable baseball player given the scarcity of catchers who also contribute offensively even if he catches fewer games than some of his counterparts. It's natural that fingers are pointed at him since he is the team's most visible player, but it's erroneous to blame him for the team's problems this year, especially based on anecdotal evidence that is easily disproven by statistics.
