Back in the 80's and 90's, maybe even up to the early 2000's, the University of Colorado had a much bigger football culture, and was constantly challenging for top 10 positioning.
Once Gary Barnett was gone, they hit a major slump and haven't shown any signs of climbing out of it, aside from a fluke year by Mike McIntyre, and a few flamboyant moments from Deion Sanders.
Right now, the Colorado faithful are actually accepting of Deion Sanders' performance, where last year's decent season (where they had the best player in all of college football) were the equivalent of a gift handed to them by God.
Also, he's actually hung in there against some of the tougher teams (Georgia Tech, BYU were by 1 score).
He actually keeps that spark of hope alive, and has improved the "home grown" recruiting by a good bit.
