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.
Professional and international non-setters often step in to set when out-of-system. You know why they are so good? Because they practice all the time!
We can't tell our setters exactly where to set every single ball. That means we have to teach them to make the right decisions in the moment.
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.
