I think that they did want to use Turner at SS but I think they were hopeful Danny would go back to.2012 Espinosa also. They definitely did not think he would be the SS this year. This offseason will be interesting because if they use Turner as a CF. We have alot of CF prospects who are defensive speed guys in the minors and nothing else.
It sort of depends how everything else goes. Like if we had missed out on Murphy and gotten Céspedes, Turner would be on 2B and Céspedes would be trying to play CF right now. We'd have a worse team, for sure, but you have to assume a domino effect no matter what you do.
Next year, obvious candidates for upgrade are SS, CF, 1B, and C. 1B is probably a non-starter, but at least Murphy is a great backup. Turner solves one of the first two problems, depending who you get to solve the other.
