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

You are kidding right? You cite the one time something happened EVER to justify hiring a coach to do what no coach has ever done before.
There have been successful head coaches who had very similar resumes to Rizzi's.

SO glad you are not running the Saints.
Right back at you brother.

In all the history that you posted on Rizzi no where does it say he was ever a coach on either the O or D side of the ball in the NFL or even a major college program.
You're changing your criteria to defend your opinion, instead of re-evaluating your opinion. That's one of many reasons I'm delighted that you have zero say in how the Saints are run.
