I don’t believe a 7 seed is sent to a site based on proximity. It’s only for the top 4 seeds of each bracket (top 16 overall)Those are seeded first, but they follow the same principles for 5-16, similarly I would expect Gonzaga to be in Spokane or BYU in SLC if they can get matched up with the respective seeds
“National Seeds
Before any games get underway, it first begins with the seeding. The top 16 teams of the tournament are assigned what is called a “national seed”. This helps shape the tournament and designate who is playing who, and where they are playing upon advancing to the next round. Each team that is assigned a national seed is granted hosting rights for the regionals round.”
