How the heck are the Eagles favored over the Saints in the Dome? EDIT Saints favored by 2.5

every draft we have to hear all about how Philly got someone else from Georgia's D, but I don't see anything to be impressed with
Jaylor Carter has been OK. Nolan Smith has been a non factor. He's best suited as an OLB'er in a 3-4,not a DE in
a 4-3,. Opponents have been running to his side with great success from what I'm reading on the Eagles sites
