It's an ironic discussion, this. Jacobs was a first baseman in the minors who didn't hit well enough to be considered a true prospect as a first baseman. So, they told him to learn how to catch, because his bat would be more viable as a catcher than as a first baseman. Now, we're debating whether to put him back at first base, because of his below-average catching skills. As a catcher, he's going to make mistakes. I don't know how well he can call a game at the major league level -- few rookie catchers can. That's a big part of the game. He's also not great at blocking balls in the dirt (from what I've seen of him), which is also big at this level, where passed balls (or wild pitches that could have been handled) are just as bad as stolen bases. Few catchers out there throw out more than 25% of would-be base stealers. While it would be nice to have Ivan Rodriguez, I doubt that Molina will save many runs by throwing out runners on steal attempts, or pick off that many runners. I'm all for solid defense, however, and a catcher who can call a good game. My guess is that the organization has already made up its mind that Jacobs is not a good enough catcher to play the position regularly at the big league level, leaving only the question of whether he's a good enough hitter to play 1st. I like his defense at 1st, by the way.
