The stress of deciding who to set during play is a real thing for setters, especially for younger, more inexperienced ones.
Awareness of what's going on around them on the court, and the implications of it, can be the difference between good and average setters.
Should your setter take every ball, or should they be able to call for help on balls far away? I actually think it's a question with a mistaken focus.
You can never discount the value of experience with respect to the performance of a volleyball team, as some stats from the Big 10 show.
How do you pick your starting setter? I encourage using performance metrics you can collect from game play, though they aren't the only consideration.
A volleyball coach recently asked for a bit of clarification on the subject of setter foot position and back-to-front weight transfer.
Use the right training focus and set up incentives to get your setter to be more aggressive (or less lazy) about taking second balls with their hands.
Reflecting on the match I coached one day while I coached in Sweden I realized I made a mistake in how I thought about and handled my subs from a couple perspectives.
