There was plenty of room for improvement in Bill Callahan's offense. And in Bo Pelini's offense. And now in Mike Riley's.
But it is utter madness to ignore the huge, historic drop off in the Nebraska defense during most of this stretch.
The defense went out and earned the right to be criticized. No idea why some here take much more comfort blaming the offense.
(I'll save you the time: I understand how offensive turnovers and stalled drives make it tougher on a defense. But that excuses next to nothing in terms of the actual problem)
