so classically you just root for whatever city your in and/or the closest city to you and/or the city your partner/family is from. for example my dad is from cleveland so i root for the browns and my dads family is in philly so i root for the eagles too. i also currently live in new york so i’ll occasionally root for the giants/jets if theyre playing. i think you should have one team you ride or die for (for me the browns) but due to the nature of the playoffs have a lot of irons in the fire
that being said if you want a winning team the chiefs, bengels, cowboys,
bills, ravens, packers (but don’t be a packers fan) are all good options
for funsies root for the raiders, vikings, or bears bc those are the best tailgates i’ve been to
