This time last year, I wrote an article about the mercurial 2018-19 Celtics in which I used an episode of the erstwhile NBC sitcom Community to discuss the wide range of possible outcomes that awaited the team across their final 34 games. It was a useful framing device for those Celtics, who, volatile as they were, seemed equally likely to either come together and contend for a title or completely flame out and collapse. Now, as the current iteration of the team enters a similar stretch, it’s worth revisiting the idea, both to evaluate what lies ahead for these Celtics and contrast them to last year’s team.
