I think at some point they should extend this SEZ structure one section to both the east and west with party/viewing decks.
Agreed
Also, I thought the reason for the NEZ design being what it is was a result of fire code and new construction regulations, not due to the parking lot.
My point was more thinking about why it looks different compared the rest of the bowl. If there are code reasons sure, but I am just saying if you preserved the same slope of the seating (just imagine taking the SEZ, mirroring it, and placing it on the NEZ) that it physically pushes everything further north. They obviously wanted (and needed) a 360 concourse, which pushes the building back further from the field.
There may have well been code issues, but IMO the building footprint, and what they were trying to achieve with the concourse, and the space they had to work with all triangulated to the design we have, and why it sticks out (not horribly) compared to the rest of the stadium.
