Especially when you're looking at teammates with wildly differing playing time.

Again, what if Molina's backup has 5 appearances that month, and had a pitcher having a great day due to a weak team etc. His CERA will be greatly skewed. Same with Molina if he is in there against the top teams.
AND say Molina's personality would work with 70% of pitchers, but he has 5 of the 30%. He will not be effective. It's all relative. Much like a catcher's arm. If a C is known for his arm, his CS% will not reflect that, because speedsters will not test him, only taking the high % SB attempt.
It's so complicated that trying to put it in a neat little formula is a incredulous
I am not an enemy of advanced metrics, but scouting,experience must not be totally dismissed in favor of them. Absolutes are never a good thing. For catchers, trust the manager and players. When they say a catcher is a good catcher in loud majority then give them the benefit of the doubt
