The Boston Celtics are no strangers to injury. This season they’ve been the team most affected by COVID-19 with 162 player-days in the health and safety protocols. The next highest team is the Dallas Mavericks at 118, making that a difference of 44. Along with that the Celtics haven’t had a single player play in every game of the season to this point, each of them missing time to tend to one injury or another.
Zero. They haven't had a single game with the entire roster available at the same time. And this doesn't include new additions like Fournier or Parker or anyone else.
