FLOWERY BRANCH, Ga. -- The Atlanta Falcons, safety Thomas DeCoud said this past week, "have been underestimated and called overrated" all season, and when you think about it, that's a tough daily double. Overrated and underestimated? On Sunday, the Over/Under Gang will face the 49ers for the NFC title. The Falcons have the better record. The Falcons will be playing at home. Naturally, the Falcons are an underdog of historic dimensions.
