New England is the most hated, and it's not even close. I lived in New England in the late 90's and went to many games in the Sullivan / Foxboro stadium. Most people didn't care, didn't understand the game, couldn't explain what a first down was. I remember tailgating with some friends before Patriots games and we like to ask random fans to name other mascots in the NFL. At least half their "fans" couldn't name more than 5 other teams. Then those arrogant f'ers start winnning and act like they're god's gift to the NFL. Plus all those despicable characters that were their leaders for those 20 terrible year. It was cruel punishment to have them play in so many championsip games
I would be glad not to see KC in the AFCG or Superbowl for at least 10 years. But I dont even hate the Chiefs 2% as much as the Patriots. i actually hate the TB Bucs way more than the Chiefs. Those idiots gleafully adpoted Brady, Gronk, Antonio Brown, etc.
The Chiefs fans are riding high in recent years. But other than a couple loud mouths in the media, I have found their fans to respectful and not over the top. Can't say the same for those Massholes.
