To me, catching is one of those things that very few are going to be good at being a two-way player. By nature, the defensive aspects of the game take so much time to do well. Not just the physical, but the mental as well in order to truly be a good defensive catcher. Between knowing the staff and knowing tendencies of opposing batters, there is a lot of prep to it. Sure, the coaching and stats staff help with some of that, but to be able to call a game well with a variety of pitchers with a variety of pitches isn't just something that is learned over night. That takes away time from working in the cage. On top of all of that, there is a physical toll that playing the position presents. Guys that can play average and above defense and still hold their own with the bat are a relatively rare breed. I think there's a reason for that. I'll take a defensive minded catcher over an offensive minded catcher any day. That position is too important defensively to be able to get by with a poor defensive catcher and expect to win consistently.
