Ok, I am a Hoosier who relocated to Illinois 15 yrs ago. Now I am stuck here! Lol
I don't have a ton of knowledge yet on HS sports here, mainly football, but my son will be entering HS next year, and it has made me start paying attention the last few seasons.
First off, the Illinois season starts one week later than Indiana. So any changes to the playoff format, would likely simply be addressed by moving the start of the season up one week.
The new proposed plan has many parents scratching their heads here, as most fans truly don't understand the idea of more teams making the playoffs (God forbid they all make it). The high number of High Schools in Illinois is balanced out with 8 classes of roughly 32 playoff teams in each class. So basically cut out one round of Sectionals (which here is Regionals the. Sectionals).
The ultimate goal is to cut down the amount of travel in the first two or three rounds of playoffs. I personally believe they all end of pre-assigning Districts of 8 teams, and the top 4 in each will make playoffs. I do NOT think they will ultimately end up having a set deal where those 8 teams will be required to play during the regular season.
Lastly, some asked why football playoffs should be set different than any other sport. The answer is simple. You can play 4-5 heck even 6 basketball, soccer, baseball, etc games a week. 3-4 wrestling meets with a wrestler having 10+ matches in a week. But playing more than one football game a week is too much to ask a HS kid. My kid plays 8th grade football and is starting on both Defense and offensive lines. Even at that age, he takes at least two days to recover and ice the bruises. We have all either seen or felt that exact thing.
