Using this post to sort of spew my random thoughts, haha. I don't mind adding extra rows onto the structure of the existing Horseshoe structure, but I think it would ideally go along with lowering the field. Even though bringing the first row of the Horseshoe down to field level would be a M-A-S-S-I-V-E improvement to the current situation, even our East/West Main stands are WAY too far from the field! Those issues unfortunately cannot be solved without lowering the field due to the players standing and blocking the view, but you have no such issue with the SEZ. Thus, I would just favor a brand new structure that gets fans as close as possible. For example, the NEZ structure is much closer to the end zone than the East/West Main stands are to the sidelines because it doesn't force itself to "match" the rest of the stadium ... and if we just renovated the Horseshoe, we WOULD have to "match" where it starts with the rest of the stands.
On that note, I am generally a fan of stadiums that are in some way unique. If we are going to keep a horseshoe setup, do it like Ohio State and have at least one end that is clearly the "non-horseshoe" aesthetic. This is nothing more than my subjective opinion, but my least favorite type of stadium is like what Rutgers has, where you have a small bowl that happens to have an upper deck only on the sides:
I find it just fundamentally uninteresting. It's too small to be a proper bowl (as LSU's Tiger Stadium actually WAS before its renovation, as shown below!), it's too round to have more of a "squared-in" aesthetic, it's not a horseshoe, etc. I would want any MS renovation to avoid making the SEZ and NEZ look too similar UNLESS both are "squared-in" and match what the East Main and East Balcony sides look like to complete the stadium's aesthetic. If we are going to keep the SEZ as a Horseshoe, I would hope we take inspiration from what LSU did in trying to give that structure as much height as possible:
Before (Field View)
After (Field View)
Before (Aerial View)
After (Aerial View)
You will notice that they actually added VERY few new seats, but now the stadium looks a lot more complete and visually imposing. I hope we prioritize creating something tall and filling in as much open space as possible with whatever we do to the SEZ. Then we can do whatever we want with the NEZ, and there is less pressure to get that end perfectly right.
