A roster opening is room, not just a departure
Every program loses seniors. That is not an opening. An opening is who leaves at your position, against how deep the squad already is behind you.
Why 'they graduate four seniors' means nothing on its own
Four departing seniors at a program carrying three goalkeepers is not an opening for a goalkeeper. The number that matters is position-specific and depth-aware: who leaves at your spot, and how many players already sit between you and the field. That is arithmetic, and it is the single most useful thing a public roster page will tell you.
Where the number comes from
We read 65,486 roster spots off the programs' own published pages and re-read them each cycle. Class year and position come from what the school printed, which is why the figure is a floor rather than a claim: a roster that does not publish class years cannot be counted, and we would rather show a smaller true number than a bigger invented one.
What it cannot see
A public roster does not show incoming commits, players entering the transfer portal, or anyone who quietly leaves in January. So this is the best available read, not certainty — and any product telling you it knows a coach's exact need next season is telling you something it cannot know.
How to use it in one sentence
The most effective line in a first email is the one that proves you looked: naming the position and the cycle, not adjectives about the program. Coaches can tell in one sentence whether you read their roster or found their address.
