I know I've shared this before, but after Frost won his bowl game with UCF, one of the Lincoln TV Stations immediately went live after the game expecting an announcement of his hiring at Nebraska. They ran old highlights, an interview with his parents, Tom Osborne, former players and so on. They did this for nearly a full hour waiting for the announcement, repeating these segments over and over. The announcement didn't happen and the reporters awkwardly went back to regular programming.
On top of that, there's the "day by day" two-part documentary that is all about the glory days of the 1990s. You'll also still see TO regularly on political ads during election seasons (and he has not aged gracefully, IMO). I've seen a handful of people still wearing their National Championship gear...yeah, pretty standard.
EDIT: I almost forgot, look up "Frosty the Coachman" on YouTube. You won't be disappointed!
