Oregon is close to Cali, and the battles over those recruits (if they want to stay out west) don’t involve nearly as many high level schools. USC is about the only one right now.
They currently have 5 roughly top 250 players from Cali, one from Las Vegas, one from Oregon, and one from Arizona. Sure, Oregon itself doesn’t produce nearly as many but Nike Oregon is a huge brand. They do well in Texas too. Chip Kelly recruited reasonably well there, and Lanning is a much better recruiter.
UT is recruiting against at least 3 (and normally 5) top 20 programs for a recruit in the states of Georgia, North Carolina, and Florida.
