I would argue that teenage girls (in particular) trying to manage interest/phone calls and potential offers from college coaches in the midst of trying to perform their best over the course of the summer--has great potential to be more stressful than just waiting to until September 1st to formally begin the recruiting process. As you said, it's just 2.5 months. What's the big deal to wait and see who has TRUE interest until then? Coaches will have a much better idea of who they are interested in recruiting after 6 weeks of evaluating vs what....one weekend? Will NY kids even play on the June 8th weekend or will they be in State playoffs and exams?

Where to spend time and money this summer? Do some homework and send your kid to camps at schools she is interested in and that could be a good fit for her both academically and lacrosse wise.

And I will repeat, if you don't think it also has the potential to wreck havoc with club team dynamics, then you haven't been involved with this long enough.
