If you want "main-stream" credible/coverage and you want the support to grow the sport long term, you will want & need the sanctioning and the blessings of the governing body. The existing lacrosse supporters and infrastructure can only do so much.
this may be true-but then again with UIL rules-who the heck is going to coach these kids? I don't know very many lax coaches that are actually teachers, which UIL requires. The immediate impact would be interesting-coaching would suffer and teams would suffer.
Many teams now are hodge podge conglomerates of area players who's players either attend a high school with no team or in some circumstances play for a different team than their own school for one reason or another-a big UIL no no.
The good side-yes the championship and league would be more legitimate in terms of an even playing field, but the down sides include just some that I mentioned.
I agree with Karl-why bring it up now, if they are not ready or willing to go?
