The bookies have Seattle as the favourites to win the Super Bowl. I don’t really agree with that - I consider Green Bay, Dallas and Seattle the top 3 NFC teams and Dallas will probably have to face Seattle after the wildcard round, so Seattle arguably have a greater chance of being knocked out before they even reach the NFC Championship (Green Bay on the other hand will have to make it past the winner of the Cardinals v Panthers match, which is pretty nice for them).
The safe bet would probably be a New England v Green Bay (or perhaps Seattle) Super Bowl.
I’d have an outside bet on a Steelers v Cowboys final. Two teams with really complete offenses, able to put a ton of points on the board, and Dallas have already shown that they can beat Seattle this season.
