With this past season in the books for the Red Sox — and all but eight of the other 29 teams as well —so is the latest decade of baseball history. The next time we’ll see this Boston team, in whatever form it takes, on the field it will be 2020, which is both mind blowing in the weird way the standard passage of time tends to be as well as something I hadn’t really thought about while the season was going on. As the decade comes to a close, it seems as though this team will be heading into another transitionary period as we enter the 2020s.
