For the third straight year, the Falcons could be facing an opponent that’s peaking at the right time. Last year, Atlanta lost to the New York Giants in the wild-card round. The year before that, the Falcons lost to the Green Bay Packers in the divisional round. Both the Giants and the Packers went on to win the Super Bowl. Even before Sunday’s 24-14 victory against the Washington Redskins in the wild-card round, the Seahawks had won their last five regular-season games and seven of their last eight.
