During the last legislative session in Minnesota, Native derived nicknames were banned unless the school in question is on a reservation and like 90% native or unless the approval of all the state's registered tribes regardless of whether or not they have an interest in that particular community.
Some have quickly complied, like Esko, which won a state baseball championship this month just before eliminating its "Eskomos" nickname, which is basically just a pun on a term that isn't even used anymore.
Others are more thorny, namely the Warroad Warriors, a community with a large Native history and population that intends to seek a waiver to keep their Native designed logo. You've probably heard of them during hockey season. T.J. Oshie went there, as did Henry Boucha (who is Native), and seemingly dozens of Marvins.
