With the whirl-wind of all the new Adidas jerseys being released, there were a few logos which changed that went unnoticed!
First, the New York Islanders added a thick blue outline around the pre-existing orange one on their logo for their away jerseys. While the Tampa Bay Lightning removed their word mark from their logo on their away jerseys to match their homes.
Finally, (the more obvious change) with the Edmonton Oilers changing up their colour scheme from royal to navy blue throughout their entire uniforms, that meant that their logo's colours changed too.
There you have it! Not major changes, but still changes which went unnoticed!
