It's just that there is a sort of "former coach culture" that is quite real in the practice attitudes, the gym habits, and the overall relationships between players and their coaches. I even saw it in the military going from one base to another; same army, different cultures. And when an NCO from one area was assigned to his next duty station, often there would be adjustments in that soldier's mind and attitude. Scott Frost brought tough, straightforward attitudes with him, and was met with a lot of pu&&yfooting around and apparently even strangely not-on-board attitudes that flabergasted him and even visiting old Huskers.
That's a difficult assignment, to say the least.
