I wonder that too.
That's why I keep bringing up scenic views. I agree that that expect that they'll likely have the interiors and immediate exteriors fully detailed. For the most part, I expect the skyline of the stadiums to be accurate. So, I'll expect to see mountain skylines for those appropriate teams, etc. I think that the schools that will have the most detailed exteriors will be the one with the open end stadiums. That's because they almost have too or it'll look unrealistic. But for the bowl shaped stadiums, I would mainly just expect accurate skylines
For the most part, the only way I see fully detailed exteriors is if we see it in a pre-game cutscene before the game. I'm not sure how over the top they will go with pregame. I expect pre-game to mainly be the pre-game stadium-intros and some pageantry stuff. But, I'm not sure how much of stadium pan overs we'll see of stadium exteriors prior to games
