The teams in the NFC have, absolutely, no say in who is going to win XLI.
Name an NFC team who will make it to the SB, and I will name 6 AFC teams that will beat them. EVERYONE knows that the winner of the AFC Championship game should just be crowned the SB winner. No one is interested in the NFC. I'd rather watch the paint dry, than watch any NFC matchup.
The only thing that the weaker Conference gets is the front row seat to a AFC SUPER BOWL WINNER show.
