Deep thought over cereal this morning. In hats/tshirts etc I think "Huskers" can stand on it's own. But, if there's a "Nebraska" involved, it should always be "Nebraska Cornhuskers". "Nebraska Huskers' looks silly.
Actually, I think this would be a good topic to bring up to Bill Moos. He seems like a guy who is welcome to recommendations and not be complete a-holes to fans like a couple of our past AD's.
