With 2015 officially a lost cause, it’s time to start thinking about 2016. Not because it beats watching a bullpen with one reliable arm that’s been worked to the point of not being reliable anymore try to get nine or more outs every night. Or not just because of that. No, if 2015 has any utility at this point beyond the comfort of having baseball available as a soundtrack to our respective summers, it’s the ability to evaluate players and test them at positions in ways that are not possible for a team that actually needs to win games.
