Incorrect. Teams dont accept 28 kids in anticipation of kids rejecting. Because then if everyone accepts, you are left with more kids than you want on the team. You put out a roster for the number of kids you want. And you have a waiting list if people dont accept.
The most you do normally is hedge your original number by 1 ir 2. Example ideally if you want a team of 21 or 22. You may put out a roster of 23 or 24, knowing if everyone accepts, its still not a ridiculous amount and you can manage playing time.
28 is ridiculous. And thats what they are looking to have because its a "money grab".
