Honestly, while I hate watching so many people start climbing the stairs with so much time left in the game - and to be fair, at least some will then watch from the concourse; this does expose maybe the biggest design flaw of Carver….there’s only a long way up to the concourse to exit the arena. They would have been better off creating the gates a la Kinnick where those exits are roughly halfway between the top and bottom of the stands.
imo, they also screwed up when they chose a major renovation of Carver a few years back instead of starting brand-new and learning from Carvers flaws.
