This guy makes some sense about uniform changes:
Changing a jersey should be as serious as changing a mascot name. Much thought needs to go into the decision of changing it, tenfold more than the amount of time a graphic design team spends fleshing it out in Photoshop. The change is not just in color and patterns, but in memories. New jerseys designate new eras, and that should span wider than the tenure of a coach, or a starting quarterback, or a calendar, which is where they’re at now.
