Not many of the state champs attend the kids series. If this is not endorsed as part of the season by KSHSAA many will not participate. Don't get me wrong, I love the idea. I wish they had as an option when my son was in HS. But they did this back in the 80's (yes along time ago), and the issues were that if their coach cannot coach them, there are no organized practices, it's optional, it's still seen as "after" the season, many will not attend.
Then is loses the luster of a "Grand State". Still would be a nice tournament for those who go, but not grand state.
