I don't even think they're trolls. Trolls don't really believe the sh!t they say, they're just trying to get a rise out of people.Neither you nor I understand the troll mindset.
I think these people are just negative people who are buffoons and for some reason gain some sence of self-importance by not being easy to impress.
They're the crowd that will only bring up things like Tanner Morgan's passing yards after beating another Big 10 team by 30. Their schtick is "call me when you beat the [insert better team here]". I think for the Gophers, they are usually MN sports fans who don't know anything about college sports.
But yeah, it's a weird group.
