The dimensions of the stadium are well positioned so no one has a terrible seat in the house. I like how the stadium is uphill, which makes it feel like you are climbing a mountain to go to the stadium. It gives it a mystical feel.
The stadium PA announcer encourages the energy from the crowd on plays like 3rd down. It would be good if there was a constant message hyping up the fans. When ASU was losing, there weren't many PA announcement to get the fans going. This would be my biggest recommendation.
