I was watching a 4pm ET west coast football game a few weeks ago and noticed the field look like it was lined up so it ran north and south. Are all NFL stadiums built this way?

The old Tampa Stadium and the New Ray Jay , both had/have the field so it runs North and South from end zone to end zone . The main seating areas are on the East and West side of the field. Does this make sense?

I was wondering cause you sometimes hear announcers saying rushers are running North or South.
