In the blowout department, I think of 2010, when the Badgers hit or cleared 70 three times, including putting 83 on Indiana and 70 on Northwestern (I was at the Austin Peay game, the first 70-point outing). They only scored 48 against Michigan, but leading 24-0 at half, they didn't attempt a single pass in the second half.
In 2011, the Badgers scored 42+ nine times. They were 2-3 in games they scored fewer than 42: Their lowest scoring game 28 (Illinois, 17) was a win, but they lost in games they scored 29 (Ohio State, 33), 31 (MSU, 37), and 38 (the Rose Bowl vs. Oregon, 45), and they beat Oregon State 35-0.
And of course, there's the 2012 Big Ten Championship Wisconsin didn't belong in, but still hung 70 on Nebraska (and also didn't attempt a pass in the second half, only attempting 10 for the game).
These kinds of scores are serious outliers for Badger teams. Side note: no Badger team since 1959 has reached the Rose Bowl in a season it didn't score at least 50 points against at least one opponent. In '59, the Badgers only exceeded 25 once (44 vs. Marquette).
