I didnt think the Eagles would beat the Falcons so I am probably off on this too, but I see one of two things happening.
1.) An extremely sloppy / low yardage / field goal game where field position will mean everything (special teams wins the game for whichever team).
2.) The Vikings completely roll the Eagles. I cannot see it the other way around at all.
When I feel so strongly about an outcome I should bet entirely the opposite way.
