In our area, a summer high school coaches league formed a couple of years ago and basically, the top players from differennt schools in the area who have not yet graduated are playing for these teams, leaving the current HS graduates and age-eligible college freshman left for sr legion ball. My guess is the jr legion took a big hit from the HS coaches league, but this is the way they're going these days I suppose.
I guess the one positive that comes out of it are those HS players who got shut out of legion ball due to politics, the secretive nature of legion rosters and tryouts, daddyball or whatever have the opportunity that they wouldn't have had without the HS coaches league starting up. If I'm not mistaken, that's a part of the reason the HS coaches league started up in the first place.
