The Boston Red Sox traded for Caleb Durbin because they could. They decided to figure out the rest later, and over a month into the season, there's still a lot to figure out. Never mind that Kyle Harrison is flourishing for the Milwaukee Brewers -- that team has some voodoo magic when it comes to developing pitching. The trade was made because the end of the offseason was approaching, the Red Sox were clearly short an infielder, and Durbin was the only name on the market with whom chief baseball officer Craig Breslow was comfortable with the price tag. We know what's happened since. Durbin has been good at third base, but his offense has been among the bottom 10 players in the league so far. Whatever potential that remains to be unlocked, the Red Sox aren't tapping into it. If you like our content,  choose Sports Illustrated as a preferred source on Google .…
