BOSTON — After a historic start to the season, the Celtics’ offense cooled off in December and hadn’t been quite the same since. There was a natural regression as opponents adjusted. The 3-pointers stopped falling. Robert Williams’ re-insertion to the lineup has been a process.
Lately, the absence of Marcus Smart has loomed large.
But on Wednesday night, the Celtics returned to the norm. It felt like November again at TD Garden.
