Your entire argument is that Bogaerts is not bad defensively based on a stat that you know is not good on small samples.
Let me make it clear here: The current edition of this team is better with Drew at SS and Bogaerts, who, no matter how much you mentally masturbate to the contrary, is not a good defensive SS at the moment.
Let's say Drew plays against both righties and lefties (which is not a sure thing, since Farrell will do what's best to the team, and you can't link enough articles to claim otherwise), considering the black hole 3B had been offensively until Holt started hitting, you actually improve on four positions by putting Drew at SS and trying Holt at LF on a vacuum. SS, 3B, LF, UTIL. Holt is a good athlete and he could be a super-utility that bumps Herrera and his uselessness off of this roster.
Based on my history on this subject, your chicken little response that is similar to Fred's usual insanity is what's wrong here. Bogaerts is not going to suddenly forget how to play SS, and furthermore, most scouts expected him to end up at 3B in the near-future anyway. This is not rocket science.
