Since the NHL switched to Reebok Edge jerseys in 2007, many teams have altered their uniforms in order to make them more aesthetically pleasing (and hopefully boosting sales among the fans).
A trend that has been occurring quite often in the past several years is that teams with popular alternate jerseys have been promoting them to their home jerseys, while creating white versions as their away jerseys (Buffalo, Edmonton, Los Angeles, New York Islanders and Philadelphia). Today, several teams with high-selling third jerseys and unpopular home and away sets still exist, and it leads me to wonder if more changes are in store in the near future.
Just to be clear, almost all of these predictions mentioned in this article are completely guesses on my part, based on the past trends as well as sales numbers. There is hardly any evidence that any of these changes will occur, other than that it has happened recently in several different instances.
