I guess my thing is...we probably shouldn't evaluate assistants that enter successful programs and are successful at those programs so highly. One thing Josh Heupel's career has shown is that the thing he's good at (developing QBs and offense) goes with him. Regardless of how good or bad a team is he makes them better, on that side of the ball at every single stop.
I don't think Pruitt's a bad DC or bad assistant coach, but I don't know if he's elite either. Because every spot he had immense success at the HC in place was doing it before he got there and after he left. Ultimately I feel like he got overvalued by Fulmer because both of them had similar mindsets to how to build a successful program. Which is kind of funny since neither has ever actually built a program from nothing themselves.
I think Pruitt will likely be a DC again and in the right place (with a good/great HC and an established program) he'll likely do well there. I just wonder if he could build a program that wasn't already full of talent.
