yeah but with a new coaching staff, you'd expect some growing pains or trouble acclimating. But that hasn't been the case with the Saints.
As for the Ravens, I think you can pass over the top on them, but running against the Ravens is nearly impossible.
The coaching staff could have been an issue, but I think bringing in Brees really helped that. He seems to be a really stable guy and very pro coach. And of course they started off winning which really helps a team get confidence in the new coaching staff.
You can pass over the top on the Ravens so long as it's a fairly quick route, they got those two scary LBs that blitz well and make teams not want the QB to hold the ball long.
