Prefer type of coach? An offensive, A defensive, or a middle guy?

Good thing Rizzi has been a position coach, DC and a HC on 2 different occasions.
Didn't you get the memo? It's no longer about Rizzi's coaching career. It's now just about his coaching career in the NFL or a major college program. CFL experiences count too, but none of Rizzi's experience outside of being a Special Teams coordinator counts, including his interim head coaching experience.

Even if the Saints go undefeated for the rest of the regular season, it won't count as successful head coaching experience for Rizzi, because he's just a Special Teams guy who doesn't know anything about offense or defense.
