I don't think that is true. If the team is winning big games and generating buzz and excitement, they will talk about it. Sure, it is never going to dominate sports talk here, but the only thing that does that is Broncos.
Buffs have been horrible for 10 years, and they haven't been relevant on the national stage in 15 years. It is going to take winning and time for them to get back into the local consciousness.
I remember the year that CU basketball turned it around, beating KSU those 3 times that year. I had a conversation with 102.3 at that time about getting some folks from Allbuffs on their radio station to talk CU basketball. I told them all about the successes from that season, the recruiting, the facilities that were coming, and that CU basketball was going to be a national player. I told them they could start getting a grasp on that early buzz.
They didn't care AT ALL. It took two more years after that before they started to talk CU Buffs basketball. Now during the season, you do hear some segments every week about the team, and about how great the Keg is for games.
CU only has themselves to blame for their media coverage.
