Vikings, 'boys, Falcons, Seahawks? Rams, Lions, who else? Mental block right now.
What are you listing?
Seahawks got rid of their dome before going to the NFC. Right now the current list of NFC dome teams is:
Vikes
Lions
Rams
Falcons
Saints
And soon to join the unable to play in foul weather club are the Cowboys and Cardinals. That'll be 7 out of 16 teams, almost half the conference will fear rain.
