NL Central midpoint report

We're nearly halfway through the 2013 season, and we've seen some good, some bad and some Josh Hamilton. This week in the KaraBlog, we'll take a look at each team at the midpoint of the season and discuss what has happened and what should happen. Let's move on to the National League Central.

Buy low: Starlin Castro is better than this. Don't expect him to hit .300 the rest of the way with power, but it wasn't wrong to originally value him as a top-5 shortstop. He's 23 and can run. In addition, Edwin Jackson's underlying numbers and track record say he's better than this.
