Most likely you're looking at hires at assistant positions where they have some connection to Marrone.
That's the way it generally works so you have to connect the dots.
A lot of this speculation is unrealistic. Just saying.
I tried looking online for team media guides for the Jets and Saints teams which Marrone was a member of but I couldn't find those.
I was interested to find out who else Marrone coached with in the NFL besides Herm Edwards, Sean Payton, Paul Hackett, Donnie Henderson, Dennis Allen, Pete Carmichael, etc.
