With a win over Utah Saturday, CU will go on to play in the PAC-12 championship against Washington.
It's been a huge turnaround for the team that had only won four PAC-12 games during its first five years in the conference.
Saturday's game is extremely close to selling out, which would be the first time in nearly eight years.
Some though have been in those stands at Folsom Field through the tough recent years.
Members of the student group C-Unit were on 9NEWS at 4 p.m and joined Kim Christiansen for a show of school pride. Watch in the video above.
