NEW ORLEANS -- If the San Francisco 49ers are going back to the Super Bowl, they will have to win three playoff games on the road.That was the situation going into Sunday's game at New Orleans and it remained that way after the 49ers lost their second straight playoff-like game.There's no doubt the 49ers were a discouraged, emotionally spent bunch as they prepared for a long, unpleasant flight home. The 49ers tamed the great New Orleans offense in its own habitat, but still saw a winnable game turn into a 23-20 defeat when the Saints kicked a short field goal as time expired.
