Mark Rosen talks an important strategy point that's often overlooked, and all it requires is close observation: The opposing setter's pattern. Every setter has a pattern they're most comfortable using to earn points. Maybe it's middle, outside, outside; Maybe it's setting the hardest set possible each time; Maybe it's right side, dump, middle.
Encourage your team to notice these patterns and then adapt blockers and defense to accommodate the setter's patterns. Smart setters will switch up their patterns in order to prevent the opposing team from exploiting and adapting to her tendencies.
