All healthy I'd want to plan for everyone under 30 minutes unless they are having a hot night. Minutes per position avg for the main rotation I list below. There is a balance of unclaimed minutes that would go to the best playing guys that night or to the end of the bench guys
PG- Irving 28, Rozier 12, Smart 6
SG- Brown 26, Smart 12, Rozier 6
SF- Hayward 26, Morris 7, Tatum 7, Semi 5
PF- Tatum 20, Horford 10, Morris 12, Theis 5
C- Horford 15, Baynes 15, Theis 10
That's an 11 man nightly rotation.
