Fans of some teams feel "entitled." When you cheer for the Yankees, Dodgers, Manchester United, etc. you expect your team to win every year. Any setback upsets the "natural order of the universe."
Many (most?) Minnesota fans feel "disentitled." They expect to lose every year. If they managed to win the division, they prepare themselves to be swept in the first round. When that doesn't happen, they assume they will be swept (or at least beaten) in the second round. Losing is the natural order of the universe.
I'm pessimistic as a defense mechanism. I expect them to lose and when it happens it's just "the way it's supposed to be." I don't get depressed or even distressed about it because it's the natural order of the universe. On those occasions when they surprise me and win, it's a wonderful feeling of elation.
I couldn't root for one of the "entitled" teams because it would be too depressing to fail most years at something you expected to win.
