Let's see...Eugene/Portland/Nike versus Los Angeles, Dallas-Ft. Worth, Austin, Houston, New York City, Miami, Atlanta, etc. Those metro areas have more NIL opportunities than what Portland/Nike can offer. The majority of those cities are east of the Rockies where at least 2/3 of the country lives.
NIL isn't focused solely on Nike and Uncle Phil isn't going to live forever. That's like saying Arkansas' players should benefit from Walmart HQ being in the area. No one shopping at Walmarts outside of the southeastern US will know who those Arkansas players are. It doesn't mean that GM will always offer Michigan player NIL deals since Ann Arbor isn't far from GM HQ in Detroit. It doesn't mean that national insurance companies and P&G based in Ohio will give Ohio State players exclusive NIL deals nor defense contractors will be doing that to UVA, VT, UMD, and even CU. It doesn't mean that Google and Apple will be exclusive for Stanford & Cal players and the same goes for Amazon, Microsoft, and Starbucks for UW & WSU. Oklahoma City is home to at least two of the largest oil & gas companies in the US and they are not always going to give OU players NIL deals. I could go on and on. Even Nike is not obligated to offer UO athletes NIL deals.
It's the local companies such as the used car lots (think Big Red Motors in Norman...remember Rhett Bomar), restaurants, businesses, etc. In those large metropolitan areas, there are lots of businesses that will be vying to get the star player into their ads so the fans who see those players will stop by for a drink and perhaps some good BBQ when their favorite team is on the road or after the home game.
Those businesses even from those small college towns with large football stadiums can still reach the alumni in those large metropolitan areas by having their favorite team's star players in those ads especially those targeted online ads. That's another way to recruit athletes in that case. UO could offer Nike but that is limited in scope and many other schools are sponsored by Nike. I'm sure Oregon has some of those businesses that happily supports those Duck athletes but if I'm a recruit that knows for certain that I can end up in the NFL, maybe UO isn't the best solution but USC is. My likeness could end up on a NYC building too. Tell me how UnderArmour has helped Maryland recruit elite athletes. And the CEO of Apple did go to a SEC school and could direct Apple advertising dollars to Auburn athletes but are there better schools aligned for Apple in that case and Apple could target athletes from those schools instead of Auburn...yep that can happen.
UO could do well in the NIL arena but again, Nike is not obligated to sponsor UO players only. Same thing for the Jordan brand and North Carolina.
Perhaps you are the one who needs to do that thinking through.
