Not sure how you are counting last year the build up when they where just in their second year of going through a tear down. Cubs, astros, and royals went through 3 really bad season before they started seeing the improvement to to start winning. Astros took took 5 season to finally get back to winning and another couple more till they won the world series. Cubs went through 4 seasons of losing before getting into the playoffs. Sox probably would be more ahead if some of the main pieces didn't get hit with injuries and delayed improvements. So if next yr they don't start seeing major improvements then you can start complaining about not see it built up enough. Sox actually improved 10 games from last yr with major holes in the rotation and lineup. Hopefully nothing but continued up from here.
