Here is a little perspective for all the Pitt fans over hear beating their chest like Narduzzi is Nick Saban.
Pitt in 2014 under Chryst with a much younger Roster.
Offense - Ranked 40th in the Nation averaging 31.8 pts per game
Defense - Ranked 26th giving up 25.6 pts per game
Pitt in 2015 under Narduzzi
Offense - Ranked 72nd averaging 28.6 pts per game
Defense - Ranked 28th giving up 24.2 pts per game
So, Pitt is technically worse in both Offensive and Defensive categories despite having a more experienced roster.
Keep in mind the ACC coastal was much better last year than this year. Duke, VT, GT, etc have all had very bad years. Adding in the fact that Pitt beat Akron this year instead of losing to them and there is where Narduzzi has been more successful that Chryst...he beat Akron. I am not trying to say Pitt has not had a good year, by their standards. I just think Pitt fans lack perspective on just how good it's been. I think next year will be an eyeopener for Pitt fans and the bloom will be off the rose.
