Seattle entered the 2013 season at 17/2 odds to win Super Bowl XLVIII, just short of the Denver Broncos and San Francisco 49ers at 6/1. This is despite placing second in the NFC West and dropping its divisional round game against the Atlanta Falcons the previous year. The Seahawks were, by power ranking, ranked the strongest team by an NFL.com analyst before the season and by ESPN analysts after the regular season. The defense led the league in points allowed (231), yards allowed (4,378) and takeaways (39), the first team to lead all three categories since the 1985 Chicago Bears.
The Seahawks clinched the NFC's No. 1 seed and homefield advantage throughout the playoffs with their 13–3 record. The Seahawks defeated the New Orleans Saints 23–15 in the Divisional round and the San Francisco 49ers 23–17 in the NFC Championship. During Super Bowl XLVIII, they defeated the Denver Broncos 43–8 for their first Super Bowl victory in franchise history.
