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

New Haven and Rhode Island ??? There are HS programs better than that!!!!
SMH
OK go ahead and name me a successful HC that had no experience being a OC, DC or even a position coach in the NFL or even a D1 school. It's never been done in the modern NFL. The closest you could come is Levy but he was a HC in the CFL before he was HC in KC , and he bombed in KC before Buffalo.
Just because you've been the boss of a successful mom n pop store does not mean you hire that guy to run Wal-Mart

There's not many examples, but they have already been pointed out to you. These former DCs and former OCs keep getting fired left and right while one of the last ST guys to get a shot has stuck for nearly 2 decades. You don't like Rizzi for some unknown reason or don't think he should get the job even though he's earning it, check.
