Many small sample sizes at the top and bottom end for games missed/played (Fultz, Fournier, Law etc).
Some other factors skew it also eg Bamba early on was sitting out back to backs and the Magic are 1-8 in back to backs, I don't think that is all just Bamba being out etc, and non rotation players likely didn't need to be listed, but I included everyone anyway.
Anyway, keep scrolling if this adds no value to your life

Conclusion: We miss DJ?

He's hoping to play in the first game post All-Star break.
