Yes, 2021 was the first time in 9 years that the PAC had 2 top 10 recruiting classes. I hope it continues.I agree with this but I'm not sure how adding SMU will help Oregon or USC recruit the state of Texas.
Honestly for the 2021 class, the PAC did a much better job at keeping players in their footprint. 2020 and 2019 were bad but USC's resurgence on the recruiting trail has helped. I don't think the PACs future is all doom and gloom. Oregon is recruiting at a level that we've never seen before and they are doing very well in the PAC footprint (landed the #1 players in Oregon, Arizona, Colorado and Nevada). USC's resurgence on the trail shows they are going to keep most of the top players in LA. If those two programs can turn those recruiting successes into results on the field, the PAC will see an improvement in their relevancy.
The next step is Washington and ASU. It is a free for all in the state of Arizona right now (to the benefit of Oregon) and ASU isn't getting any top in state talent. And a lot of it is leaving the conference. You get Oregon and USC to being consistent top 10 teams and Washington and ASU to consistent ranked teams and the PAC is back in business.
