Volleyball defensive specialist benchmarks: what each level actually looks like
These are the numbers Athlete Quotient scores every volleyball defensive specialist against - not a coach's opinion, and not a chart copied from a message board.

These are measured sport-wide rather than by position, so they apply to a defensive specialist the same way they apply to anyone else on the roster.

How to read these
Each column is a level, not a cutoff. "D1 average" is what a typical D1 defensive specialist does, which means roughly half of them are below it. "D1 elite" is the top of the distribution, not the entry price. Being under a column does not close a door - it tells you the size of the gap, which is the only number you can actually train against.
