I don't disagree with the goal of what you're saying. And this isn't directed at you, because I think we're both in agreement with the real problem. But I'd be totally against this idea because I'm tired of all the rainbows and unicorns in cheer. And I think something like this would just *further* dumb down the sport. We already complain about too many divisions, too many Nationals, etc. Cheer needs a slogan soon, that says something along the lines of "Everybody can compete, and everybody can win!".
I agree with all the counterpoints to the "It's about the growth of the sport.". Funny how it seems that every competition I went to this year, EP's are on blast about how it's been the biggest turnout ever for their event. My daughter is 5 feet tall, and probably not destined to grow much taller. I'd say volleyball is NOT in her future, no matter how much she'd like to. But I'm sure as heck not petitioning for a 5' 6" and under league, that caters to kids with so-so hitting skills, playing on a 6 ft net!
Not everybody is cut out for every sport. That's just life. And if you don't treat the top of the food chain as elite, then you're completely doing a disservice to the spirit of competition.
