Whose ball? Seam responsibilities

In the post On player communication I talk about the challenge of players communicating with each other on the court. It, in part, brings up the question of whether players really need to talk during play. That’s from the perspective of player responsibility. In other words, whose ball is it?

With that in mind, I will share my own personal basic philosophy on seam responsibility. I’m happy to hear about different approaches.

Starting principle

I take as my starting point the idea that the person with the shortest distance to go for the ball should take it. After all, it will take them less time to get there. Flipping that around, it means the player farther away takes the deeper ball. Generally speaking, it’s easier to go sideways or forward than to have to try to go backwards to play the ball.

Serve receive seams

Here’s what that looks like in terms of serve receive. The star is the location of the server.

So as you can see, the player who is closest to the origin of the serve is the one who takes the short seam between players. The one further away then takes the deep seam.

Defense seams

And here’s what that same principle looks like from the perspective of a standard perimeter defense. Again, the star is the attack point.

Of course you may use a different type of defense or locate your defenders differently in the perimeter scheme. The concept remains the same, though. The important thing is that players understand that the principle applies regardless of court position. They need to know instinctively who has the short seam and who has the deep one in all situations based on their relative positions. If they do you will drastically reduce the number of balls that land between players who are standing there looking at each other.

Beyond serve receive & defense

Now, understanding seam responsibility when in serve reception or in defense is only part of the equation. There are other “seam” situations that should have clear rules. Here are a couple that come immediately to mind.

• Who plays the third ball over between a front row player backing up and a back row player moving forward?
• Who takes a ball that is set between two attackers?
• When does a middle hitter take a serve?

Then there are other situations which influence who takes a ball, such as the setter releasing on a free or down ball. Or when you want to let a key attacker release. I’m sure you can think of a few of them.

The point is, the players should understand these structural elements of how they play, as I talk about in this post about whether calling the ball is necessary. There will always be situations that don’t fit into nice, neat structure, but if the players know the principles, they can deal with things effectively. When they reach that point, talking becomes less about communicating in-play and more about communicating between plays.

How to train seam responsibilities

Once players clearly understand their seam responsibilities in concept, training them to become automatic is a matter of repetition and reinforcement in realistic situations. That means against actual serves and attacks (though they can certainly be at reduced speed).

The biggest issue I see when it comes to seams with younger players isn’t that they can’t/won’t talk. It’s that they haven’t develop the ball tracking capabilities yet. They literally don’t know whose ball it is. So yelling “Talk!” at a pair of teammates who let a ball drop between them isn’t helpful (see To call the ball, or not to call the ball). You need to get them to work out between them whose ball it was to reinforce the expectations. And give them lots more opportunities to practice dealing with balls in the seam, of course.

FAQs

Who should take the seam ball?

Use the seam rule your team is teaching and make it consistent. The key is not having a clever rule; it is having a rule everyone recognizes fast enough to use under pressure.

Should seams change by level?

Yes. Younger or less experienced passers often need simpler, more fixed seam responsibilities. Stronger teams can adjust more based on passer quality, server tendencies, and personnel.

What if one passer covers more court than the others?

Then your seam rule should reflect reality. Equal-looking passing formations do not always mean equal responsibility. If one passer is clearly stronger, build that into the coverage and teach it explicitly.

How do I teach seam rules quickly?

Use one simple rule, define it in plain language, and repeat it in the same serve-receive contexts until it becomes automatic.

Why do seam rules break down in matches?

Usually because of pressure, movement, hesitation, or mixed standards about what counts as a playable first contact. Players may know the rule but still fail to apply it at match speed.

How do I train seam communication under pressure?

Use drills that force live reads and then score the behavior you want. Start with Serve Receive Drills That Transfer to Matches for reception. You can do something similar for defense where you put a defending team out against hitters intentionally trying to hit/tip balls into seams.
