Again you need to cover you a$$ so to speak.

If you are going to be the one giving the team points, I would want to know I am following the rules first. I was involved in a situation recently where a team had jerseys for years that were illegal and they were totally shocked they got penalized. And they were shocked considering our state focused on this more than anyone. They deserved what they got and should have known better for sure.

If I do not want to lose a customer or piss them off, then I am going to know what they can have legally. The same way I would not sell a bat in baseball that did not specifically follow the regulations that are current and one of the reasons I see radio ads from a famous retailer selling BBCOR bats because they know those are the only ones legal at the NF and NCAA level. And next year this is going to also be a nightmare in football as their are new regulations for football uniforms. And they have used the last 4 or 5 years preparing all involved that this rule is going to change and that penalties will be adjudicated if uniforms are illegal. Something tells me that schools have already not paid any attention to this rule even though has been on the Rules Video required viewing by all schools and official and if they do not know these new regulations that will go into affect in 2012, shame on them.

In a perfect world, manufacturers would know the rules and would clearly mark them in their catalogs. But it ain't a perfect world.

Yes, the burden falls on the school. However, there's usually a middle man, a local sporting goods sales rep. He should know what he's selling his clients, whether it's legal or not, and advise accordingly.
