The unveiling of a team's new kit is a summer tradition, and it's a cynical one. In the US, minor design changes are made and alternate jerseys introduced simply to spur fans to spend more money. In Europe, there's that, and there's a brand new sponsor to plaster across fans' chests.
So give Partizan Belgrade some credit for reverting to just an Adidas patch, even though it's just as large as the team's crest. And feel free to wonder why they didn't get a one-piece mannequin.
