Things I know, and things I think I know:
Some Nebraska football fans long ago grew tired of hearing Scott Frost and even Bill Moos talk about how much the "culture" in the program needed to improve. I understand fan skepticism in that regard, but only to a certain extent.
Bottom line, I don't grow tired of the discussion. It's an extremely important discussion as Frost's program prepares for its third season. Plenty obviously has been lacking in the program in recent years, including a winning culture and strong player unity. How hard do I have to sell this?
