I guess this narrative is here to stay. Wasn't the problem that Middlebrooks wasn't any good? Wasn't Drew the option that was available for cash and was (ostensibly) a known quantity? I don't have any interest in defending that set of moves by the FO, but I have a hard time believing that that they lost faith in Xander, shoved him to third, and then rediscovered their faith in the off-season (early on, since Sandoval was signed on 11/25).
Let's momentarily give the FO the benefit of the doubt. Let's assume that they just wanted to fix 3B and chose to temporarily do so by bringing back someone they knew to cover a difficult defensive position and moving their highly-skilled, prized prospect (again, temporarily). They had seen him play some third base (granted it was not many innings). It's regarded as a less physically demanding position than SS, and thus would be within his ability. Importantly, it keeps him on the field and gets Middlebrooks onto the bench until they can find a new 3B. There are certainly other ways that they could have solved the problem they had, but let's assume this story, since it's basically what they said in the media. In this situation, do you think that no one spoke to Xander and explained exactly what the plan was? Especially if you believe that the psyche of a top athlete is so fragile that they could be shaken by being moved to a different position (or that adapting to that position is a distraction from other components of the game), don't you think that the team would be careful in their treatment of someone they have repeatedly stated they regard as a cornerstone of the team going forward? I know that people want to find an explanation for what they see based on the minimal information they have, but I can't buy this story of the psychological mistreatment of Bogaerts. It requires one to believe that the people running the Red Sox don't understand how to work with baseball players. The results in several recent seasons notwithstanding, I don't believe that. I do think that recent evidence (Bogaerts, Holt, Ramirez, Betts) suggests that the Sox don't think that adapting to a new position is that onerous a task.
