I wouldn't put much stock in all HS player rankings of many sports EXCEPT it actually impacts college coaches. Lacrosse HS hype machines are very powerful for the connected schools/clubs. And lax coaches completely rely upon club programs to be de facto recruiters for them.
In a time when lacrosse is booming in terms of HS play across the country, the recruiting circuit has actually narrowed. Look at top lists-- the same school and club name dominate the list. College coaches have very limited time or resources to properly screen recruits. They rely upon showcase lists, rankings, tourney appearances, etc.
Amazing how a club-owned property like NLF pretends to be some source of talent evaluation. It's an inside job. And it's working.
