They weren't able to do it this year with the new entrance for the team. I found this in e-mail from the Jr CyclonemClub earlier this fall:
PS As you all know, the Cyclone football team is now housed in the shiny-new Bergstrom Football Complex. Which means their entrance into the stadium will be through their new tunnel leading them from the complex to the west ramp and onto the field. This also means that we are longer able to have our exclusive Jr. Cyclone Club field access prior to kick-off at a home game any longer. Due to the Cyclone’s new team entrance from the northwest – and the visiting team’s new entrance onto the field from now the northeast (and factor in both teams crisscrossing to their respective sidelines), it is now logistically impossible to make a Jr. Cyclone Club “tunnel” to greet our Cyclones and then exit the field in a timely fashion before a penalty delay. We’ve exhausted all ideas and efforts at this time for a Plan B that would work. Bummer, I know.
