My feeling is that it would take lots and lots of money to pry Narduzzi from Pitt in 2020. Which asks the question do you want pay Pat Narduzzi lots and lots of money?
He's been developing Pitt's defense for years now and at least on paper it looks to be stacked. I think he wants to be around it for this year at least instead of what looks to be walking into a messy situtation at the last minute. In 2021 if that's your guy, I think he might be interested.
If Fickell says no just give it to Tressel in the intern or go save Matt Canada (who really did a good job in a worse situtation at Maryland) from having to coach meathead on the Steelers.
