Fact is, attendance at college football games is down across the board. There's a few of the legends like 'Bama, LSU, Michigan, etc. that haven't felt it much, but for the most part, it's down all over the country. UW needs to look at the factors involved, hone in on the possible legitimate reasons, and act on the actionable ones.
TV is a huge factor. TV exposure is exponentially broader in CFB. Add in the hassles of parking and the disdain factor for any one or combination of drunk/ unruly fans, misguided law enforcement/ security, lines for everything, uncomfortable seating, dry stadia and it becomes pretty clear. We haven't even approached the economic factor as well as the fact that, like it or not, live sports venues and stadia are now competing with sports bars and lounges offering multiple games on big screens and even private screens in a more comfortable and managed environment with fewer hassles at prices far below the stadium experience. This is the landscape of college football, and, to a certain extent, basketball (arena comfort isn't as negative).
I think the programs need to think about how to take a page from the sports-hospitality providers and figure out how to deliver an experience that provides more comfort and value while mitigating inconvenience. Price models probably need some shifting along with offerings and added-value amenities. Stadium security should be handled privately by well-trained personnel whose focus is guest comfort and satisfaction along with safety with law enforcement on stand-by and augmenting security, largely in service to security management, not treating fans in attendance as someone on public property. They should react on complaint, not on observation (leave that to private security).
As far as amenities- I think first and foremost would be in-stadium broadcasting of TV feeds for smart phones and tablets/ pads. These should be replay and pause-interactive along the lines of current DVR technology. Enable apps to order concessions from your seat, delivered by servers. Alcohol is available in the Wildcatter- make it available in certain sections with strict ID verification enforcement (bracelets, etc. and zero tolerance on providing to under-age or cut-off fans). Hell, take a page from Petco in San Diego and set up a bar and grill in the north end zone and offer two seatings. I can think of a half a dozen things that would make the experience more attractive to both the casual fan of average means to the rabid fan in the upper-income tiers.
