The Eagles have beaten the Lions, Jaguars, and 49ers, a combined 3-11 -- all on the road. They've lost to the Redskins and Packers, both 3-2 NFC contenders -- both at home. Last year Philly went 6-2 at home and 5-4 on the road (yes, they earned one of those five in the Georgia Dome), so don't expect that home field disadvantage trend to continue.
A better way to look at this: the Eagles are 3-0 in games in which either Michael Vick or Kevin Kolb throws every pass, and 0-2 in games the two passers split.
The Falcons, meanwhile, have won ugly for three straight weeks after blowing out the Cardinals and losing to the Steelers 15-9, a '90s baseball score. Atlanta has looked more impressive so far, though it hasn't been forced to (and/or willingly elected to) use a quarterback rotation.
