They changed the type of paint that they use when they switched to the new helmets (which I love and wished would look that nice in game). The process they use to paint them is too complicated for the managers to do in one night. The old paint used to chip off too easily because they would have issues between it and the solvents they used to clean and maintain the spray guns. Not a big issue for me as an ND fan.
Now these abortions they are wearing in Chicago, on the other hand... I hate them. The helmet is terrible and a disgrace. The only things I don't want to burn are the cleats and gloves. It makes me long for the Champion days.
