tl;dr: I think the IHSA multipler seems to work and perceived recruiting at privates is just that, perceived; privates would have been out-ed and IHSA would've sanctioned them if it was true. IMHO, Coach Holecek wouldn't consider taking a college HC job

I'm a long time lurker but only recently a registered member. Full disclosure I've put all of my kids through LA. I'm one of the outlier zip codes mentioned earlier as I live in Chicago.
As mentioned earlier, I don't remember the board taking issue when Stevenson beat LA last year (except for the fact they met in the 2nd round), or when Bolingbrook or Naperville Central beat them in the State 8a Finals (Though I do remember a NC bus having a home made "God Loves Us for Free" sign on it...very classy). The IHSA multiplier is the equalizer that forces privates/Catholic schools to play up a level(s). Why does it seem okey dokey and perfectly normal when a private loses because the public was better but outrageous when the private is ranked #6 in some computer poll most of us don't even agree with anyways (I think the poll also had BR at 95, HF at 96 iirc so judge for yourself). I guess the bottom line is the multiplier seems to work. It's not perfect but unless you want to go to separate championships, it's seems the best system. Hypothetically, if we really want to be fair, why don't we have an equalizing factor for wealthy suburban schools with the money to have great equipment and coaching vs poorer schools that don't have the funds or boosters to support the same. Doesn't sound great but in a way that's what privates have to deal with.
With regards to recruiting, if you look at a varsity roster, I think you'll see many of the kids coming from north shore schools, most went to catholic schools and as Ignazio mentioned, many coming from OLPH. I don't think it's recruiting when many of the starters come from OLPH, easily LAs main feeder which is next door in Glenview, less than 3 miles away. It's reasonable to assume if they're coming from Catholic elementary/middle schools, their familys would send them to Catholic High School as a preference. If people think private/Catholic HS coaches are violating IHSA recruiting rules, I think the market forces would have out-ed them awhile ago. And as far as scholarships go, many (and I mean many) at LA get scholarship money which are all needs based (required to fill out a FAFSA-type form).
A little off topic but with regards to Coach Holecek considering a Illini HC job, I don't think so, I don't think he'd want the headaches that go with it and I think he's happy where he is
