nice try Gom. Small sample size for one. And for two, no matter how "bad" Posada is behind the plate, he does not make up for the significant offensive dropoff. Sorry Gom. If they were close offensively, then I would be on board. But when you talk about 300-400 points of OPS, then it is not worth it. If you really want to try and make a case, you'd go back through ERA in games Posada caught since Molina arrived and then of course get the ERA in game Molina caught. Then, you'd have to break it down further based upon pitcher to see how much of a difference, if any, there was between them on a pitcher by pitcher basis. If certain pitchers have a massive dropoff going to Posada, then you have a case for Molina being a personal catcher. Otherwise, I think you'll find it hard to find a significant difference over a bigger timeframe.
