I considered that. Just because I think the shift from Madison to Lambeau only drops the difficulty modestly (Lambeau was effectively an equally long trip into unfriendly territory, and Wisconsin still jumped around...and they then played the same dang team) doesn't mean I think fear can't be involved at all. I just disprefer that you are completely ignoring the other factor.
Money is one of the factors at the forefront of the neutral game trend.
Meanwhile, the bigger detriment to UW at Lambeau isn't venue intimidation but the fact that the players can't sleep at home. Any travel, even in-state, somewhat knocks one out of one's groove.
