Saints hire Terry Joseph and Kyle Wilber

Looks like it. This is going to be a really important hire since the matchup zone/pattern matching coverage with a 2 high shell is going to be a fairly new concept for our secondary. I'm sure we have used similar things from time to time with DA, but we played a lot of man to man and often with single high. This is going to be a big change that is going to need to be taught well by the DB coach. Also, IIRC, one of the biggest issues the Staley had with the Charges was with the coverage so hopefully Joseph is ready for the step up to the NFL.
Important to note that the Fangio defense doesn’t necessarily play in a two-high shell, the signature of his defense is to be in one pre-snap. The safety that rotates down for cover 1 or cover 3 has the advantage of playing from depth and seeing the play develop in front of them, and that puts them in a better position to disrupt a lot of dig routes and crossing routes that have been a headache for our defense in recent years.

It’s also advantageous against teams that want to run a lot of play action, because the QB will see one thing pre-snap and then see something completely different when he turns his eyes back downfield.
