* No central registry: There's no single national database tracking all high school lacrosse players and their subsequent collegiate athletic careers.
* Variable participation: The number of high school lacrosse players varies significantly from year to year and state to state.
* Definition of "play": Some players may be on a D1 roster but not see significant playing time. The definition of "play" impacts the calculation.
While you won't find an exact percentage, it's safe to say that it's a very small percentage. Division I lacrosse is highly competitive, and only a fraction of the many high school players aspire to and achieve that level. It's likely in the low single digits, perhaps less than 1%.
