I'm putting the AFC North because that is mostly what this board is comprised of, fan-wise. Other teams are in the link...
[h=3]AFC North[/h]
Baltimore Ravens: Baltimore stole Cleveland's team. I suppose we could try to understand that if Los Angeles or Sacramento did it. Those cities could claim they didn't know better. But
Baltimore? After all those years of crying because the Colts left town, how could Baltimore steal another iconic team from a city that loved it desperately? This is like Elin Nordegren cheating on her next husband with a waiter from Perkins.
Also: Ray Lewis.
HATEABILITY FACTOR: 10
Cleveland Browns: They suffered for years. They lost their team because they wouldn't build a taxpayer-funded stadium. They got so angry, they were promised they could keep the team's name and (empirically speaking) ugly uniforms. They built a new stadium. They watched their old team win a Super Bowl in a new city. The new team has mostly sucked. Their archrivals have won six Super Bowls. You can't hate the Browns unless you cheer for another AFC North team or are a jerk.
HATEABILITY FACTOR: 2
Cincinnati Bengals: The Bengals have an unusual approach to building a team. Instead of acquiring "good players," they have focused on players that nobody really likes, ideally those with a criminal background, though selfish players who are past their prime also fit the mold. The Bengals have also chosen to alienate their starting quarterback, save every possible dime and demand loyalty from their players instead of inspiring it. Astonishingly, this has not worked.
HATEABILITY FACTOR: 4
Pittsburgh Steelers: Your instinct is probably that you should love the Steelers. They are supposed to stand for old-time football. Does any team match its town better than the Pittsburgh Steelers? They are named after an industry. They are all about toughness and passion and doing things the hard way. They have had three coaches in the last 50 years.
But they also employ a quarterback, Ben Roethlisberger, who has been accused of sexual assault multiple times; a running back, Rashard Mendenhall, who questioned whether the 9/11 attacks happened the way America believes they happened; and a star defensive player, James Harrison, who should probably avoid speaking in public, and also in private.
HATEABILITY FACTOR: 9, mostly because of Roethlisberger.
