The Bengals make the playoffs every year lose in the playoffs every year in 1st round (they have lost the last 6? in the 1st round though missed on the playoffs last year because injuries) even when the Bengals are the vastly superior team. The Bengals also always lose to the team the fanbase hates the most, the Steelers. As an added bonus they also lost to the Steelers a couple time in the playoffs, in both halarious fashion and with their star QB getting his leg shattered by said steelers. Also on Bengal home games against the Steelers 1/2 the fans at the game are Steeler fans.
As a Viking fan you will inevitably get your hopes and expectations raised at which point the Vikings will then devour your soul.
Kansas City is a more competent version of the above 2 teams and Andy Reid is a good coach who somehow has no idea what the hell he is doing in the last 5 minutes of every single game. As a NFL neophyte you may not understand clock management but my god you will immediately understand clock mismanagement. They will lose every single playoff game due to inexplictable head scratching moves in which Andy Reid runs out the clock on himself. You will curse god and hate your coach with a fury unknown to man. Only you will never fire Andy Reid because as I said before, Andy Reid is a good coach and will take your team to 11-5.
