Three surprising NFL lines---can anyone explain??

[Tyler Durden]

All lines are on WPEX:

Eagles +7 at Cowboys
Ravens +3.5 at Steelers
Saints +3 at Giants

The Eagles, Ravens and Saints all seem to be good bets here. I am surprised that the Saints are dogs to NYG given how poorly the Giants have been playing and they've lost 5 of their last 6. I understand their backs are against the wall but the Saints are still playing for a first round bye.

Also, for the Eagles game, it seems this game will often be closer than 7 pts, am I wrong?

thanks much.
