There are still some fine points to be worked out. The league has exclusive relationships with corporate sponsorships, which means teams wouldn't be allowed to sell that real estate on the shoulder to competitors, even if the price is right. Lists like those need to be drawn up before teams' marketing departments start pressing the flesh. After that, teams will need lead time to approach potential sponsors, then reach deals with them. At that point, adidas would affix the patch onto all jerseys sold for retail.
Fans who don't like the patch will have one recourse: They can refrain from buying those jerseys. More likely, that 4-square-inch patch will fade into the background because, when a sport is healthy, the event takes center stage.
