The coaches are targeting players who have a don’t quit attitude, a strong desire and capability to learn and improve, and have skills that can be successful in complex offensive and defensive team play.
It’s not that a player can pass well or rebound well or dribble well or shoot well. It’s a player who can see multiple things happening on the court simultaneously and quickly process better and best options in a constantly dynamic changing situation and make the right plays.
Good peripheral vision, good reflexes, good stamina, good motor, good strength, ability to learn quickly, ability to process multiple things quickly and effectively are valued as much if not more than athleticism and individual skills.
Nowell exemplifies this. I’ve watched enough of his play to know he has his own variation of team play that we see in Solo, Tristen, Stephon, Cam, Alex, and Hassan.
