I think they are far superior in the trenches, which is the most important part of the field. Their secondary is the biggest weakness, but it's been light years ahead of where it was last time the Eagles made a trip down to NO, while the Saints are trotting Eli Apple out as their #2 corner.
Out of receiving threats, Thomas is the best between the two sides, then the Eagles have the next best 3. QB and RB, Saints have a significant edge (but then again, can't explain Foles in the 4th quarter). I think it's certainly close because of how well the O-line and D-line of Philly have been playing.
