To give Koz minutes without taking away from Mag and Catchings, you'd have to move someone to the 3. This would take away minutes from Knell and Saunders (our returning players).
Giving Crawford minutes would push more of Egor's minutes to the 2 and 3, which would decrease the minutes to Baker, Knell, and Saunders.
The whole point is to give returning players close to 60% of the minutes. To get that, you have to give freshman less minutes.
