I understand all that, but I think the difference is you anticipate some of these roster reduction acts being really overt and there being a big uproar by the community and association.Under the BEDS count system there is no need to run kids off or limit participation for the sport. Since they are counting the total number of kids in grades 9,10 and 11, whether you have 50 kids out or you have run off 20 and now only have 30 does not matter, your classification would stay the same.
Even with the system of looking at free and reduced lunches factored in, it would not matter. The only way running off kids could get you down a class would be if they were grouping by actual roster size, which I think they should do, but its never going to happen. Then it would be possible to run kids off to drop, but by doing so, the coach and the district is going to create a **** storm of bad press and the state assocation would get involved.
Maybe in some cases, but big schools cut now in sports. It's done at a coaches discretion, and the association has nothing to say about it. And coaches also do things that reduce roster sizes that are not so overt or explicit. In some cases these are needed and make sense. You need to have standards as a program. But I think it's also pretty easy to run a program where kids aren't cut, but have such a poor experience that they don't go out, even if a kid is doing the right things.
Not as applicable to football, but I know of baseball and basketball programs that don't "cut," but they have many kids that never see the field in game action at any level. No matter how bad the blowouts are, no matter the situation. My daughter played in a 5A varsity, JV and JV2 game all in the same night years ago, all in blowout wins, and while there were kids at all levels that never saw the court. As far as I know most of those kids that didn't play were in good standing, showed up to practice, they just sucked at basketball. I'm not saying that it's always wrong to do. Programs need standards, and some kids are going to get very few opportunities. But these similar methods can be used for the wrong reasons pretty easily if there's an incentive.
