FLOWERY BRANCH — A slip of the tongue gave away Atlanta coach Mike Smith’s focus. Smith was just starting his review Monday of the Falcons’ 30-28 win over the Seattle Seahawks in the NFC divisional playoffs when it became clear his thoughts were on this week’s NFC championship game against the San Francisco 49ers. “We knew the San Francisco Forty ... excuse me, the Seattle Seahawks, were a very good football team and they showed a lot of resiliency,” Smith said before smiling after catching his verbal miscue.
