Before Shaw, for certain, there was strong concurrence among NCAA administrators, coordinators, etc., to keep all NCAA officials 100% uniform, not only in the WORN uniform, but in mechanics and game administration. One coordinator, in another attempt to install himself as the king of officiating, and without seeking any sort of approval from the CCA or National Coordinator, had his referees wear white hats with black piping. That only lasted one season. He was told, in no uncertain terms, that this was unapproved, and the entire NCAA was reminded that all officials were to be dressed strictly in accordance with the CCA Manual. That coordinator eventually moved on the NFL (VP of Officiating), where he continued his quest for the crown. He tried hard, but never quite got the crown, as he desired it. He has been "repositioned" a couple of times, but has managed to remain in a position of influence, in the background, over the progress of officials in the league. At least one of his brilliant "on-field" mechanics concepts was quickly abandoned by the current primary officiating leadership. I will say that this individual is not universally...let's say 'appreciated'...in his current environment.
Considering this new hat logo issue started in the conference where he had been coordinator, I can't help but think he had something to do with it, even if just by suggestion. In conference championship games last week, I know I saw one other conference with their logo on the officials hats. I'm guessing Shaw will have to address this in one way or another, before next season. At the very least, if not completely prohibited, I would hope logo hats would be limited to conference games only. But, my guess is that, in today's "anything goes" atmosphere, logos will be allowed by officials working at sites within their home conference. I suspect there is some money changing hands behind the scenes, i.e., uniform supplier provides the logo hats, plus some compensation, in exchange for those conferences to use their hats and/or other items.
Time will tell.
