Price also had that 1997-98 run in year 9, with 2 bad years before it and 3 bad years after it.
More generally, I agree with all YakiCoug wrote regarding the Pac-10 being easier to handle back then. I'd also add, just to preemptively counter anyone who would point out that Leach has good facilities and Price didn't, that I don't think it's that simple.
Leach no doubt has median facilities in most respects in the Pac-12. They're not the best in the conference, despite what Moos may say, and in particular, he has no dedicated (or appropriate) IPF. From informal looking around at other schools, I'd say they're pretty good and solidly Pac-12 level, but probably middle of the pack in the conference. They're quite good and better than what Price had for certain, but it's not like WSU now has amazing facilities which means that Leach should be able to pull in top-5 classes in the conference every year. All schools in the conference have good facilities.
All schools also have highly-paid (and, mostly, pretty good) coaching staffs in the Pac-12. Who's the worst coach in the conference ... Rich Rod or Wilcox (a little early for him, I'd think), maybe? Perhaps Graham, Helton or Mora (despite the latter being a douchebag, he was viewed as a pretty good coach a few years ago, at least)? If those guys are the bottom of the barrel, the overall standard is pretty high. Without looking, I think all those guys I listed as the candidates for the worst coach in the conference all have won 10 games in a season at their current Pac-12 schools other than Wilcox, who is taking over his first program.
I also think it's harder, all else equal, to recruit in the Pac-12 today. You have what seems to be more kids in the Pac-12's footprint willing to go out of conference, and it's harder to keep undiscovered or lightly recruited gems under wraps in today's world of recruiting, even if it might be somewhat easier to find them in the first place. It's a lot harder to keep the big fish from poaching your recruits in today's day and age, and more recruits *seem* to be focused on collecting offers and taking the biggest one. I know it's always been like that to an extent, but it seems worse now. I also think -- but have nothing to back this up, admittedly -- that kids focus more on academics today than they used to, so you might get, say, a kid with a 4.0 GPA in California who might be more apt to go to Duke or West Point (or Princeton, apparently, in the case of Brevin White) than WSU, perhaps unlike 20 years ago.
