Lot of things here that I agree on....with the big exception of lumping in fans as being part of the problem. Fans are consumers....they follow excellence...they do not create it.Have you ever run or managed a business. Cultures are real and exist. When a particular culture exists, new hires typically regress or improve based on that culture.
It's not a cheap excuse. Sometimes something gets so ingrained in a system, it becomes constant. You can start at the fan/alumni level. Maybe we don't demand enough or donate enough as a whole. Then go to the athletic department. Maybe an excuse is more convenient than a mirror. Then the university level. Maybe the excuse is more convenient than another worry. Then the legislative level. Maybe focusing on other boogeyman is more important especially when constituents aren't complaining (back to fans and alumni).
If there was a culture of excellence Burman would have been reassigned a while ago. Bohl's seat might have been warm some years rather than saying the mediocre years were better than we had before so don't complain. PBJ likely wouldn't have been hired and most certainly been fired. The culture allows this...from fans to legislators.
A couple things...
Culture ≠ "accepting mediocrity" ... Having a good culture is really really important. When we say we want a good culture we are actually saying we want good people....there is no such thing as culture separate from people. The reason there is not a culture of excellence at UW is because there are not excellent people in charge. As simple as that is....it's really hard to change it. Excellent people are not just lining up to take on the problems of every crap organization. Also, some problems are not sensitive to the quality of the people tackling the problem. Now, the problem of winning in the game of college athletics is not one of those problems. We need excellent people. The levels you pointed out (with the exception of fans) are all places where excellent people can make a difference.
Ultimately when you put down your three word explanation of everything and actually get into describing causes and effects, you make a lot more sense.
I think we could easily describe a situation where somebody comes into leadership at a company or University that hates, hates, hates mediocrity and is completely dedicated to stamping it out but can't make change or actually makes things worse....This actually happens all the time. Highly successful driven people (in sports and business) fail so often. Is this because they secretly accept mediocrity?...of course not...they are just wrong or uninformed or up against insurmountable odds or fill-in-the-blank with a billion other reasons.
