Agree, somewhat, with Virginia coach. High school comp should end with the State meet. Then it should be (if it wasn't such a lame organization - and that is on Hightower) up to USATF to organize National meets for this age-group (Junior Olympics). They could easily tie this in with selecting the National team (age-group juniors for XC, so College age) every other year as well, instead of doing it in February. The age group normally dealt with in HS is Youth in XC (from a world perspective), which then alleviates all the whining about being too old as well.
The NXN meet is an artificial "club" meet anyway. Footlocker has become what it is, because the USATF hasn't the vision to create something that would supplant it. No wonder so few "real" clubs exist, which goes on to hurt post-collegiates unless good enough to get a pro deal out of College (and there are only a handful of those opportunities anyway).
The system is broken, and only USATF (from a national perspective) should be able to change it, as HS federation rules will never allow a "real" HS championship - these are just invitationals (even with qualifying criteria) that aren't really HS meets anyway - just corporate advertising (Nike/Footlocker).
I personally prefer the Footlocker format as it is simple, but individually focused, which denies the team aspect of XC. That FM can win the girls title without a single person being in the top 45 (so not an all-american in the collegiate format), says that something is wrong with the meet. It is trying to be a NCAA clone (although that meet includes plenty of foreigners), but doesn't match it.
