I think it's a big of a chicken an egg scenario. A rabid fanbase wouldn't have allowed some of the leadership that we've had over the years to endure very long, but one of the reasons we don't have that rabid fanbase in the first place is we've never had a long sustained period of good leadership.
For whatever reason, the leadership quality seems to ebb and flow, and with it goes the football program. And worst of all, CU chose to have some of its biggest incompetency just as college football was jumping into the modern big money era.
I'm not at all of the opinion that there is a chicken and egg scenario. Leadership starts from the top. It is completely unrealistic to expect the fans to lead from the rear.
A scenario where fan leadership might work is where there is a single very wealthy fan that is embraced by the university, and that sugar daddy gets to call the shots. Think Boone Pickens or Phil Knight. Even this scenario isn't healthy, as shown by Joe Jamail and Red McCombs turning the Longhorns into an ineffective back slapping big cigar smoking country club environment that squanders talent and treasure.
CU has a leadership problem. The de facto guru of CU is Bill McCartney. That man hasn't been an employee of the university for a couple decades. Yet his ring gets kissed by every AD and coach that comes after. Big Mac is the prized key note speaker of recruiting luncheons, far out shining the Chancellor, the President, the AD, and various coaches who have come and gone. If Benson or DiStephano were even half as charismatic and passionate about the football program as Bill McCartney, this program would not have fallen so far, so fast.
No fan or fan affiliation can outweigh the leadership power of a Tom Osborn or Joe Paterno or Nick Saban, or Urban Meyer, or Bill McCartney. In each case, these great coaches had / have administrators who open up the checkbook and put a sustained premium on the importance of football success as the most visible symbol of university power and might.
Success won't take root with 50,000+ fans. Success requires a single focal point who can tell us who we are, where we are going, and what it takes to get there. It's the fans job to help the leader realize that dream.
Blaming the fans is just an excuse and a sure symbol that the people drawing the salaries are in over their heads.
