I don't root for other teams, just against them. So this is who I'm rooting against:
Bills: Grew up a Jets fan, so their inability to win a SB, despite having great teams, makes me happy.
Bears: Seeing them win a SB would be like being a 90's Vikings fan, watching the Cowboys win it all.
49ers: I don't want to see any former Panthers get a ring. I'm petty like that. (Darnold wasn't here long enough to count, and played for 2 other teams before joining Seattle)
Patriots: Yes, they're less hateable than they used to be, but they're still the Patriots.
Jaguars: I used to think of them as expansion rivals, but now I don't think of them at all. Still, I don't want them to get a ring before us.
