I don't buy it. Here you had a Wisconsin team who was 7-5 and third best in their division going up against a Nebraska team who was 10-2 and first in their division. Wisconsin struggled to score. Nebraska in a couple games struggled to stop their opponents from scoring (UCLA and Ohio State). If Nebraska was constantly giving up 30 to the teams we played, I would be behind you if you said that Wisconsin was going to score 30 or more. But that wasn't the case.
It's hindsight bias. You didn't know that we were going to get thumped, because it hadn't happened yet. Only by getting thumped could you see the reasons why we could have been thumped by the Badgers. But nothing leading up to that game suggested it.
