Team's better than the record currently indicates. I'm not terribly concerned.
Injuries and chemistry (due to injuries) have played a big role.
Health is the biggest hurdle facing this team right now.
More like "all the time." Like, from the time KG's knee got messed up until this very day. So frustrating. I can't be certain from memory, but in all the time since KG got hurt, I'm not sure the Celtics have ever gone even like two months with no significant absences due to injury.
It's really amazing—amazingly sad—when you think about it.
The Heatles went four seasons relatively unscathed (10-11 through 13-14), and the Warriors did likewise from 14-15 through 17-18. The 2019 Raptors had to load-manage Kawhi but had no major injuries to work around. And the Lakers were fine last season and so far this season.
Meanwhile, Boston's had season-altering injuries to KG, Perk, Rondo, the O'Neal boys, Kyrie, Hayward, Kemba, Smart, and probably others I've forgotten. It would be nice to get even one season free of that stuff.
