A different thought lightly touched on here is the concept of a team that supports each other in the field and the clubhouse. Players who have matriculated through a team's MiLB system and then to the parent club may have good friendship's... or not but they do know their strengths and weaknesses on/off the field. They also were trained , or not, by the same group of coaches who supposedly have a common thread, such as the Red Sox way, if such a thing exists. You know, win one, lose one.
In this apparent reset year, and for many reasons, the clubhouse has had a revolving door with free bus tickets to Worcester. There is little continuity to the batting order, fielding positions are reversible jackets, and predictability is at a premium.
I wonder if any of the shortcomings including defense, baserunning and plays-not-made come from poor communication, and unfamiliarity. Some have pointed out that our players are not "units" with plug and play characteristics. They are real live people who are looking for some consistent direction. This is more Bloom's issue of building a team than to Cora's use of them, but both have their foibles.
