Marko needs time to adjust but right now its probably better to invest on court time in Dillon and Grayson. They are already adjusted to NBA speed and defense.
It's pretty difficult to try to develop 7-8 young guys at once. Especially for a rookie coach. IMHO development minutes/patience should be in this order
I put Kyle Tyus and Dillon so low because we basically already know what type of players they are. Josh will be high on the list once he is available. However, the point is that is a LOT of young guys to develop for a rookie coach. Really an almost impossible task. I bet the determining factor for TJ will be who is the quickest to catch onto his schemes. Brandon Clarke will emerge as an important player quickly.
Marko better find his deep ball touch quickly. Because he really doesn't offer much else as of now.
