The only information about them we have is that the team isn't particularly concerned with giving them any real playing time for development.
I dunno about Hunter, but Rozier, Mickey, and Young, at least, have torn up the D-League enough to tell you they're too good to get much out of experience down there.
Draw what conclusions you will.
You're right, though -- this is the drawback to having all of these picks. Nice in theory, and always useful as assets until you actually have to turn them into players. But if you don't want to go about the dirty business of developing the guys you draft, it's kind of like planting your vegetables and then never picking them off the vine. They'll end up as compost.
