Probably for the best.
Marcus is a polarizing player, but he'll be important come playoff time as a bench scorer. Rest him as much as necessary in December, January, and February now that the team has banked quite a few wins.
Jaylen, Jayson, Semi, and perhaps Nader will all get more time. Probably some more minutes for Theis, as well.
Marcus has bailed the second unit out of some spots with his individual scoring. Could be an issue, but the team can afford some such issues.
