As a coach, it's a tough situation. For someone like DJ, you HAVE to tell him to attack, to be aggressive, to play confident. That's the only way he can reach his ceiling. Kinda similar with CJ Frederick, even when he's slumping and missing shots, you still have to tell him he has the absolute green light. They have to play with confidence and freedom in order to produce.
DJ just has to navigate those waters. For example, he should NOT take 3's early in the shot clock, but he can take 3s. He can NOT take 3s off the bounce, but he can take kick-out 3s. He doesn't shoot from the perimeter at a high enough clip to take 3's other than feet planted, kickout ready shots
