The opposite hitter, sometimes called the right-side hitter, plays across the rotation from the setter — when the setter is in the front row, the opposite is in the back row, and vice versa — which keeps a setter available in the front row whenever the primary setter has rotated to the back. In attack, opposites work mainly from position two on the right side of the net, frequently receiving back-row sets as well as front-row ones, since they are less often used in serve-receive passing than outside hitters and so are more available to attack from deep.
On defense, the opposite is usually a team's primary blocker against the opposing team's outside hitters, who attack from the mirror-image position on the other side of the net. That combination — significant attacking load plus the toughest one-on-one blocking assignment — makes the position demanding both physically and tactically.
Rarely a passer, often the release valve
Because opposites are usually kept out of serve-receive rotations to protect them for attacking and blocking duties, they are frequently the hitter a setter turns to when a play has broken down elsewhere and a simpler release is needed, giving the position an outsized role in a team's transition offense.
Why the position sits directly opposite the setter
The rule requiring the opposite to always occupy the rotation slot directly across from the setter is not an arbitrary convention — it is the mechanical foundation the entire position depends on. Because rotation is fixed for a set once chosen, guaranteeing the opposite and setter sit opposite one another is what guarantees a setter is always available in the front row on any rotation where the primary setter has cycled to the back, since the opposite simply takes over the front row while the setter operates as a back-row setter for that rotation.
