These are good points.
Challenge(s) for WSU are, in addition to all the structural challenges and the difficulty in finding someone who can do those things, is that anyone who can do those things (i) needs a good staff to support him in doing them, with those assistants getting poached, and (ii) himself will be poached eventually.
Thats True to a point.
If Leach had followed Price, instead of Doba, Wulf, and if Rolo were to be a AWESOME coach and woukd have followed Leach following Price, is there any doubt that WSU would have gradually, eventually gone 9.5 wins a season every year, season, and either a Holiday Bowl, Alamo Bowl, Rosebowl, Cotton Bowl, Fiesta Bowl, almost every season or every other season?
Thats what would have happened for 13 to 23 straight years, and WSU would have become the next semi blue blood ish football College.
So because of that WSU can become a DESTINATION Football college, instead of a Stepping Stone.
But it would take 2,3,4 legendary coaches staying 6 to 13 years, each, back to back to back, and having at least Leach level success at WSU for. 17 to 33 straight years.
It doable, but not easy.
The best chance was after Price, and WSU Admin, AKA Rawlins, etc, BLEW IT.
The next best chance is now, if Rolo ends up being almost as good as Leach, and if he Rolo were then followed up with a Leach Level replacement, followed by another Leach Level Replacement. Doable, but not easy, but still possible.
