When the 2015 Vikings broke through to win their first NFC North championship since 2009, they did so with a victory against the Green Bay Packers at Lambeau Field.
When the 2016 Vikings tried to salvage a spiraling season, they embarrassed themselves with performance and behavior at Lambeau Field, providing another easy victory for a Packers team that has surged past the Vikings to the NFC title game.
When Jerry Kill's stronger Gophers football teams climbed toward national prominence, it was Wisconsin that acted as a glass ceiling. Glen Mason, Kill and Kill's replacement, Tracy Claeys, lost their last 13 games against the Badgers.
In 2009, the last near-great Vikings team thrived because of former Packer Brett Favre, the greatest Border Battle crossover star of all time, ahead of former Brewers star and current Twins manager Paul Molitor.
Favre's best season became the high-water mark for Brad Childress, who was fired after a blowout loss to the Packers.
The Packers have been one of the NFL's most successful franchises since Favre came on the scene in 1992. The Badgers football team has been a powerhouse since hiring Barry Alvarez away from Notre Dame in 1990.
What might gall discerning Minnesotans the most, though, is not the difficulty that Wisconsin football teams have presented but the disparity between the Golden Gophers men's basketball program and the Badgers.
Saturday, the Gophers basketball team will play its biggest game in years at Williams Arena. The opponent: Wisconsin. Of course. Because for aspiring Minnesota teams, Wisconsin is the bouncer standing in the door to success.
