While I understand this goes against the RG's  expressed editorial views, I think this is a good agreement.
As I white guy, I don't believe this decision belongs to me or any other group of my fellow white folks.   Indian culture belongs to Native Americans and it is up to Grand Ronde to decide if they want to allow  Banks to do  this.  I support any policy which  Indians feel empowers Oregon's tribes and honors their culture.  Having worked with both Sue Shaffer of the Cow Creeks and Esther Stutzman of the Yoncalla Kalapuya I understand Indians differ on this issue of names, as is their right.  I expect both Banks and Roseburg HSs will develop curricula emphasizing Native culture and history, something  ALL Oregon HSs should adapt.
On the other hand I noticed the Confederated Tribes rejected Reedsport HS's request to also use the "Braves", and wonder if they  failed to work with the local Kalawatset, or Lower Umpqua, on learning about their interesting culture and history.
