Unfortunately the buck stops with the team to show up before the fans will come back. If the Buffs get a win against ASU, I would expect an immediate lift in ticket sales before the next game. A close game (dreaded moral victory) would at least allow those in attendance to feel good about at least seeing CU play well. A big loss, ala the past few years against ASU, and the exodus will continue.
It'd be great to have a sold out stadium every week, but the program has to face reality. Money doesn't grow on trees, people have to make discretionary decisions. If people are going to drop a few hundred bucks on something they probably don't want to feel demoralized or embarrassed after-the-fact. If the product improves, they will buy in again. Huge props to the fans on here, and not on here, who continue to pony up despite the struggles the past decade. May you have front row tickets when the Buffs return to the promise land!
