Exactly.
That's the poop stain the Gophers need to remove from their resume. They'll shoot up the rankings if or when they get a road win or two vs. anyone other than Nebraska (if that game is played).
The NET is far from perfect, no ranking system is, but overall I'm fine with it. There always will be outliers like Colgate & Penn State (overvalued) and Western Kentucky (undervalued), but as someone else pointed out the Selection Committee is smart enough to sniff those things out. Case in point NC State 2-3 years ago with its fraudulently strong NET ranking getting left out of the tournament because of its laughable non-conference schedule.
The key is don't get obsessed with a TEAM's individual ranking. What's most important is how a team performs vs. groupings of teams. ... Quad 1, Quad 2, etc.
