We have a school up hear in the Portland Area (I'm sure they are not the first) but they have written in there Uniform Supplier Contract that if for any reason the jerseys, pant, or other products are found to be non-compliant with current NFHS Rules as of the date they are manufactured, the Uniform supplier shall reimburse the school the entire amount of the purchase plus an additional 25% penalty.
I would think if every school were to follow suit it would put a damper on these snake oil salesman.
When I was at Russell Athletic, in all our contracts, we guaranteed our uniforms met the rules at the time of manufacture. No 25% penalty, we would simply have to replace them. We never replaced one under this clause. If you wanted a design that we did not think was legal, you had a sign a waiver saying it was your design, not ours, and we weren't liable.
But it is also why we, along with the reputable manufacturers, worked with the NFHS on uniform rules. I'm afraid to say, Kevin, that one of your large corporate neighbors did not usually attend those meetings, and felt they were big enough to "adjust" the rules.
Now, anyone with access to a fabric manufacturer that has sublimation printing (a glorified ink jet printer) can create these monstrosities.
