The request you made in your first sentence is fulfilled by your second sentence. You ask to be shown where you said 1-32 seeding would solve anything. Then, your very next sentence states you hope 1-32 seeding will solve the problem of uncompetitive championship games.
Your frustration with the never-ending debate over the public/private situation is understandable. That frustration results, at least in part, with you writing: "Either put up or shut up...". Several of the posters to this board have responded over the years by offering very comprehensive proposals to address the issues. They have, to use your words, "put up". However, they have done so with the understanding they are among the least influential individuals having an interest in the matter.
You, on the other hand, have some level of connection with quite a few high school coaches in the state of Illinois. Have you ever thought about submitting a comprehensive solution/proposal yourself, "putting up" so to speak? You could develop your own proposal or adopt one of the several excellent proposals that have already been posted to this message board. As a man of some influence, you would be providing an opportunity for Illinois high school football to be improved, as you have already done in so many other ways. Developing your own proposal may be a larger commitment than you would want to make, but forwarding (to one or more coaches) one of the proposals that have already been posted would only take an hour or two out your busy schedule. Doing so could potentially prove hugely beneficial. It is understood that the coach(s) would not likely be authorized on their own to submit a proposal to the IHSA membership, but they could work with their athletic director and principal to do so.
Letting the chips fall where they may is more easily done after one has made a good faith effort to solve a problem.
