DENVER – No one should be surprised that the Super Bowl favorites are already out of the playoffs.

With their 38-35 loss in double-overtime to the Baltimore Ravens on Saturday night, the Denver Broncos became the ninth No. 1 seed in the last eight years to go down in the divisional round.

On Sunday, the Atlanta Falcons nearly became the 10th before escaping Seattle's upset bid in a 30-28 thriller and becoming just the seventh top seed since 2005 to advance to the conference championship.

Among the top seeds to have fallen flat in the first playoff game are a 15-1 team, three 14-2 teams and five 13-3 teams — all at home, coming off a bye and facing an opponent that had to travel following a win on wild-card weekend.
