I hate all of the following:
Vikings
Cowboys
49ers
Bears
Seahawks (this goes back to Holmgren, touchception is just the cherry on top of my hate for them)
Patriots
Broncos (I'm still bitter)
Buccaneers
Rams (I grew up in St. Louis, the whole greatest show on turf bollocks was insufferable)
Falcons
I also would love to see the Panthers fail miserably due to Cam Newton.
I'd hate the Lions but they're just too pathetic for me to care.
