I didn't say they should trade away every good player, just don't over value your best player. Every team needs more than one really good player. If you can turn 1 into 2 and not get significantly worse in the short term, make the trade. Depth is still a major concern, and post season success is further away than 2015 or 2016. Brian Dozier is the best 2B in the system by far, but how much of an impact does he really have? 3.8 WAR in 2013 is significant as an individual contribution, but 4 more losses or 4 more wins makes no impact in the quality of the team.
