I realize Colorado has been bad the last several years. And the rivalry, should you want to call it that, is no longer. But from the time Tom Osborne retired, they had played Nebraska fairly close in most games.
In the 13 games from TO's retirement to Nebraska leaving the Big 12:
Nebraska has a 9-4 lead
7 games were decided by single digits
3 of Colorado's 4 wins were by double digits.
Seems they played up when we faced them. But again, this is different. The players today were as young as 11 when we last played. Not going to be the same hype, I'm guessing
