Also, it’s as likely the Sox did all that despite the catching, not because of it. The outcome doesn’t justify every aspect of the journey.
Sure, but there has been no rumor of the Red Sox being interested in improving their catching at all this offseason. The only catching rumors have been whether they might trade Swihart and not carry 3 catchers again.
Seems like if they thought the catching situation was "one of the worst positional situations in baseball" they might try to improve it. Even if they thought that they won last year despite a bad catching situation, seems like there would be rumors of them trying to improve it. There's been plenty written about them trying to improve the bullpen, for example.
If they dump Leon or Vazquez at any point this offseason, then I will agree that they thought the position wasn't good enough. Or even if there are multiple reports talking about how they want to bring in someone better, then sure. I haven't seen anything like that reported (other than some fan speculation, which is pretty much worthless.)
Otherwise, I think they are happy with the catching, and they should be, as catcher defense has a huge impact on pitching and that doesn't come across in BP defensive runs saved or whatever.
I highly doubt that the team thinks their catching situation sucks, even though a lot of fans seem to.
