What do you expect the AD to say at the beginning of a season?
Last year was a tough season, and the response was to present a unified front. The AD made it clear that Nebraska was throwing more resources than ever before behind the program and that the current staff had all the support it needed. The current staff acknowledged this, there were many cat moments, and all in all the red carpet was laid out. All Bo had to do was go out and turn in a good year, a step forward, and a lot of wins.
If that doesn't happen and this season again ends with a whimper, I can't see the AD doing that again. Last year was a not-so-subtle "one last chance." If Bo doesn't take a step forward, it'd be an endorsement of the status quo.
The tricky gray area will be hit if Nebraska wins an uninspired, sloppy finale against Iowa. I can't see Bo being canned without the opportunity to break through #4losses. That just doesn't set up the next coach very well, in my opinion. Knowing our luck, that's exactly what's going to happen.
