Well as has often been mentioned in baseball a Manager has one major function, to get the team to coalesce as a unit...to make a whole that is greater than the sum of its parts......that combined with the way the Manager handles the pitchers is just about the whole job.
However I should point out that the more the FO hands off a team of highly paid, long term contract, independently minded ball players, the less chance the Manager has in blending them into a whole. The FO must as one of its functions, keep the numbers of long term contract players at a minimum or have a highly respected player willing to accept a leadership role riding herd on the other big ticket players.
Just because a Manager at the AAA level is able to get his team to coalesce effectively is no guarantee that he can do it at the ML level. If anything it might hamper him at the ML level depending on the team the FO puts together for him. If for example the FO is embarking on a youth movement, bringing up numbers of the players from the AAA team, then bringing that Manager along with them might make a good deal of sense or If that Manager was at one time, a leader as a player and is respected for it, that might work.
I thought it interesting that the Sox PR machine is starting to spin out the story that V has earned the respect of some of the players through all the strife and turmoil of this year. Don't know if they are sending up a trial balloon or not. Who can tell with this bunch.
Nothing would surprise me anymore. They might end up bringing the football coach over from England to Manage the Sox and send V over there to manage the football team. Certainly would be keeping within the spirit of their usual nonsense. They could claim that they hired the right guys all along but just stuck them with the wrong teams at first.....congratulating themselves the whole way for having figured it out in the end.
