I know a lot of UNC fans can't or won't be objective when it comes to Duke, but I will be- primarily because I loathe NC State- not Duke- and also because I just have a lot of respect for Duke University itself. What Duke has done to invest in their football program over the last 5-10 years is really impressive, IMO. The Yoh Football Center, the indoor practice facility, and the completely reimagined Wallace Wade Stadium are all fantastic. The gameday experience there is lightyears- and I do mean lightyears- ahead of what it was 10, 15, 20+ years ago. My very first in-person college football game ever was at Wallace Wade as a middle schooler in 2001- one of my school friends' grandparents had Duke season tickets and took us to a game against Florida State. And at that time, even as a middle schooler, it was apparent to me that Wallace Wade was a dump- the track around the field looked amateurish, the concourse was awful, the seating was bad, the crowd was sparse, etc.
It might as well be a completely different stadium now. The concourse is fantastic, the individual seatbacks are great, the concessions are really good, the whole gameday experience is excellent. And the new Blue Devil Tower premium seating area is as nice as any in the country, IMO. I would argue that Duke has done just as much to invest in their football program over the last 10 years as Carolina has, and maybe more so.
