Not sure why it matters. It’s Narduzzi’s duty to the program and himself to cast the net then hire who he thinks will be best for the job. Tons of guys don’t get jobs all over the country - it’s just part of the business. And he deserves no special consideration being an alum. Coaches don’t need to be “Pitt guys”. They’re all nomads and will become Pitt guys the day they’re hired. Then will be (insert university name here) guys at their next stop.
However, if by chance this was a “courtesy interview” and he had no chance that’s another matter. I would imagine a time or 2 a coach blew someone’s doors off and got the job but by and large I think doing that is stupid. And insulting.
