You are the main communication outlet on the court between the front row and back row players. If you need the passers to get a higher pass for you, tell them. If your hitters are too early, tell them. You have the best view of the game, so let your teammates know what is working and also what needs to be changed up. Also, as a setter it’s important from a leadership standpoint for you to be selfless. Ask what do your hitters need from you? Do the need your sets quicker or further? You won’t know what to change unless they tell you, so communication is imperative.
