That’s a great sentiment and I’m sure it still holds true in certain places. ... Most catholic schools pull kids from many different areas and don’t have a feeder program that runs the exact same offense as the high school..
And this is exactly why I believe you hear less complaining about private schools and multipliers in the smaller classes. Smaller towns with stable programs who operate efficiently run the same offense starting with the 5 year olds...so the kids have 10+ years in the system when they get to high school. In many of these towns, the youth coaches played in the high school system, so they know exactly what is expected and how the base plays are run. Unfortunately, you also know who the QB will be in 6th grade. It is why the 3A powers of the state generally have coaching staffs who have been around 20+ years...
As well, many of the "spread" teams are really read-option run first programs to set up the pass. See, for example, the Juice Williams Rose Bowl Illini, or Ohio State. Illinois kids are probably not watching the wacky WAC...err the Mountain West, and more likely to watch Oklahoma than Baylor or Texas Tech. Wisconsin's power run is fun to watch... And some kids like to watch the academies triple option...
Even your traditional high school power run programs have integrated some sort of read-option to the high school system. Wilmington, for example, has been known to pull out the spread formation in the second quarter against Westmont and practice running the read option (real effective with a pair of all-state wings)...A lot of the Wilmo QB runs are actually QB read-options out of the double wing, although generally run inside the tackle rather than outside. Manteno, on the other hand, when the line is good is actually a run-first read option team...the last couple of years, however, poor O-lines have forced Haines to go empty set, running mostly jet sweeps and QB keepers (I foresee a return to the run-first read option this fall)...
