Now you're stretching.
I don't know where you came to that conclusion, but I've been a booster in town for quite a while so I see what we buy and how much we spend on it. We've (as long as I've been a middle school football player in the early 90s) had Riddell helmets in my town. For several years we used the Riddell Speed-Icon which tons of college and NFL teams use, and 2 years ago we switched to the Schutt F7 which is an amazing helmet--and also ridiculously popular with "money-no-object" NCAA and NFL teams. We had the option through our supplier to buy all 40 at once or phase it in over two years; there was a significant savings to go with the whole shot so that's what we did. They retail for around $600, in the quantity buy we came in at just over $320. Our color is solid and we did the vinyl ourselves, and got to choose how many of each size and 3 different face mask options. This is in an average-sized Iowa town between 5,000-10,000 with an average size athletics budget (ours is actually small compared to the Christian schools here).
Bottom line, every high school in Iowa I've ever come across is using a variant of the Schutt F7 or Riddell Speed series, and a big majority of Riddell schools have gone to the SpeedFlex model which is like the F7.
Saying "the helmets aren't that good in HS" is kinda bullshit and from someone who deals with it I'd say you're uninformed at best. Helmets are the absolute last place anyone is going to save costs. Get some info if you want to make statements like that.
And I'm guessing that since you know high school helmets are subpar, would you care to divulge the Iowa schools you're talking about? I'd imagine their ADs would probably like to retort. It's only fair.
Better yet, maybe you should join a booster club and see how equipment, supplies, band instruments, and travel are really purchased and paid for instead of making bad assumptions.
