I understand that SS has been an issue for the Sox for awhile now, but at best this seems like a short term solution, and not one I would readily endorse.
Pedroia has established himself as one of the premiere two-way second basemen in the game. The last time he played SS was in 2006. Three years is a large gap. And if he struggles at SS, I'll bet he tries to overcompensate at the plate.
The FO put themselves in this position, and now they want Pedroia to bail them out. If they had any sense, they would leave him alone.
