Directly after doing the hitter vs. hitter drill, Penn State often runs a variation. Here, the variation is middle vs. middle. Same idea as hitter vs. hitter, but the setters are required to deliver the first ball to a middle instead of an outside hitter. Points are scored by the offensive team only if the kill comes from a middle.
Making this drill even more challenging, the defending team can get 2 points if they block the middle for a point on the first play of the rally.
Like with hitter vs. hitter, middle vs. middle is not only good training for middles but also for setters, who have to figure out a way to be successful even when the defense knows which position is getting the ball.
