Functionally, this high school stadium is probably fine, but architecturally it is AWFUL. They have managed NOT to integrate function into a design that is focused on football AND also supports one's desire not to feel abandoned in a desolate environment. We have deserts which we can escape to for that.
The thing about these currently popular pedestrian concourses with food and other stuff, like bathrooms, is to allow you to continue pay attention to the game, while getting food, drink or having a pee break, not to indulge your restless inattentive nature, and so they are a good thing. They just need to be done right, like at Huntington Bank Stadium. Otherwise, that stadium is mediocre architecture at best (I'll explain later if asked), and I hope NU will do much better.
