It's not that, it's that the majority of Castro's defensive miscues have been on throwing errors, and I figured moving him further away from 1B isn't going to help him that much more. I know he has a strong arm, but I've always assumed his accuracy was pretty sub par. Plus his range would play well at 2B. Meanwhile I've assumed Javy needed to work on his glove while his arm was basically a howitzer, hence why his defensive profile works better at 3B than 2B (in my head anyways). To be honest I'm not too familiar with the primary concerns of the Javy's defensive game, and just basing this off what I remember from his scouting profile around his first season in pro ball.
