Well this was the depth chart you wrote -
Schroeder/russ/carter
Lavine/monk/ellis
DDR/Nique
Keegan/Eubanks
Sabonis/max
Even if you assume Carter and Nique don't play. Where to the minutes come?
Schroder (28) Russ (20)
LaVine (24) Monk (24)
DDR (20) LaVine (9) Keon (15)
Keegan (34) DDR (14)
Sabonis (34) Eubanks (14)
This would be a disaster but it's the closest thing I can find where all the starters get their mins and Keon plays. An absolute disaster in terms of size and defense.
There's no legit path to Russ being on this roster without at least 1 of Demar, Monk, LaVine getting shipped out.
