Seahawks and Broncos book Super Bowl spots

Next month’s showdown between the Seattle Seahawks and the Denver Broncos now means that just twice in the last 20 seasons have the top seeds in the NFC and the AFC successfully navigated their respective conferences.
The Seahawks won a 23-17 thriller at home to their arch-rivals, the San Francisco 49ers, on Sunday night while earlier in the day out in Colorado, the Broncos enjoyed a dominant 26-16 victory over the New England Patriots, giving quarterback Peyton Manning a third trip to the Super Bowl.
