Nike and others have done this in Football (soccer) for years! Decades by now.
Every single year the top teams of every significant league has a redesign main, a new color second and a creative new third and some teams have a fourth kit.. is crazy
The new treand, since FIFA has specific rules on what a shirt can be, is to be creative with worm kits. They do their best to expose teams worming up and in their practice facilities with those.
Is really annoying and nba is kind of infected by that now, since they will make so much money from merchandise every year that makes it worth it.
