Greetings. I'm en route to Atlanta and looking at the San Francisco 49ers' NFC Championship Game matchup with the Falcons from a few angles.First up: a look at how Falcons quarterback Matt Ryan has played at home, compared to how the 49ers' defense has played on the road.There have been some unusual performances for both.Ryan threw five interceptions at home against Arizona this season. The 49ers' defense struggled on the road against Minnesota's Christian Ponder.
