This is a great rundown and some good points. I'm aware of the history, likely more than most. I think the picture is much more complex, though, when it comes to cross-era comparisons and WSU's ability to win in the current environment.
No disagreement on the conference right now in terms of talent and ease of winning. I think right now, as in today, the Pac-12 clearly is there to be had. UW has a weak coach, USC has (had) a weak coach, Oregon is good but still can be beaten, and the rest of the conference simply is weak. Even UCLA, which might be the best team in the conference (and if not better than Oregon, seems like the best in the south), just lost at home to Fresno State and a 3-star QB who couldn't get on the field at UW. Arizona State and Utah, two of the better programs in the south, can't beat BYU, which was supposed to be retrenching a bit this year and isn't all that talented. I get it. In the next few years, though, I expect the conference to improve as a whole as Kelly continues to build UCLA and USC finally makes a decent hire. UW probably will let Lake blame the current mess on a coordinator and give him at least this year and the next, but it may move on, too, and it probably will get a decent coach. Point is that it almost surely will get harder to win in coming years even if it never has been as easy to win the conference as it is today.
More generally, I appreciate the history and significance of what Price did. Today, though, you have a ton of factors cutting against WSU's ability to recruit and retain talent and otherwise win (e.g., scouting services, social media, NIL, unfettered transfers, increased attention by recruits on things like the extent of "networks" and academics, huge money at other programs leading to all kinds of personnel who help with recruiting, scouting, and scheming, all of which they can afford to a much greater extent than WSU ever could). The FOB is great but it's not like it allows WSU to beat other P5 programs out. Even MWC programs have decent FOBs now. It was just necessary to keep WSU in the mix. I think you may be a lawyer ... it's like saying our law firm should be able to outrecruit peer firms because it has nice offices. Well, everyone has those. They're necessary to stay in the game but don't change our position vis-a-vis our competition.
All of this, especially social media, cuts against WSU recruiting substantially. Not to say earlier coaches' jobs were easy--far from it, especially going back to the times when WSU wasn't even playing in Pullman and there weren't scholie limits like today--or that they didn't face other challenges, but each of these is meaningful, and when combining them, they are tremendously impactful. I grant that the portal creates some opportunities, too, but like all this stuff, even if WSU found a way to do very well with the portal, we would just see 60 or 70 better-positioned teams do whatever WSU did, but better, and use their greater resources to hire away whatever coaches or other staff WSU has who are getting it done.
I don't want to make this too long, so hopefully the brief allusions suffice.
