Well calling Schwarber up this season is mostly a move to benefit the 2015 Cubs, even if you think he'll never play an inning at catcher in MLB he could still stand to work on OF defense and his bat probably has a tweak or two to work on. So if you're pessimistic about this year's postseason odds, then there's no urgency or immediate reason to bring up Schwarber. If you do want to maximize the 2015 roster, there's a bunch of options. Coghlan, Alcantara, Baez, Schwarber, a trade, etc. Between them I don't think that Schwarber is the far and away best option(or even narrowly the best option) for 2015, so I'm not in a rush to throw him at LF. It's a bit of a cop out, but these types of decisions are what the front office is paid big dollars to ensure they get the best production, so if they do call up Schwarber we should be pretty confident that they lovelovelove his bat. I thought everyone did lovelovelove his bat. And why wouldn't there be a reason to bring him up this year if they're not going to make a run? It seems like the argument is that he wouldn't necessarily be an upgrade because he'd likely have to adjust to the change, so why put that off? The reason I'd want him up working through that sooner rather than later is because I don't think they're going to be truly competitive later in the season.
