The NCAA went to the 2" stripes because they wanted to differentiate NCAA officials with others (mainly high school). If HS ever goes to 2" stripes, the NCAA will not be happy. They will then come up with something else that we have to buy.
By the way, the 2" stripe shirts are very comfortable. I think it would be a good idea for the apparel manufacturers to make 1" stripe shirts with the same material that the 2" stripes are made of.
