With one game left in the preseason this is my guess at the Cs regular season rotation and minutes distribution (when healthy)
Irving 35MPG, Rozier 13MPG
Brown 11MPG, Smart 30mpg, Rozer 7mpg
Hayward 35mpg, Brown 10mpg, Tatum 3mpg
Morris 30mpg, Tatum 18mpg
Horford 32mpg, Baynes 16mpg
Total minutes
Irving 35mpg
Rozier 20mpg
Brown 21mpg
Smart 30mpg
Hayward 35mpg
Tatum 21mpg
Morris 30mpg
Horford 32mpg
Baynes 16mpg
