Small improvements: I think the ones that Whitman said would come in the next few years at the 2023 media round table are all the ones I'd say we really need. Those being improved wifi and cell service, new scoreboard, upgrading to LED lights, and a new sound system, and IIRC, the sound system is meant to be stadium-wide as opposed to the two big speakers on the scoreboard. The current sound setup I have to imagine sucks for the people in the horseshoe with how loud the speakers need to be so it can be heard in the north end of the stadium. The only issue I can see with any of these is insiders have talked about the DIA locking down funds until they know how to move forward with revenue sharing, and if that freezes money for assistant coach extensions, I imagine it also freezes money meant to go to small improvements like these that aren't absolutely necessary (like the refurbishment of the East balcony supports). Iirc the work on the east balcony that occurred this summer was the first part of the improvements announced at the 2023 round table, and the next part was probably the wifi upgrades. So while all of these are supposed to be coming, who knows if they're going to be here any time soon.
Big upgrades: The big one we essentially need and has been talked to death on here whenever the topic comes up is fixing the SEZ. In a perfect world, I think we should build what we initially announced around 2017. That rendering would fix every issue we currently have with the horseshoe. It was tall, encompassing, closed in the SEZ vertically as well as in the corners, and most importantly IMO, would bring the wall as close or closer to the field than the NEZ is (one of the best aspects of NEZ actually). We don't live in a perfect world tho so I'll happily take a scaled-down version (which is probably what we would have gotten 5 years ago anyway). Something like what Iowa did with Kinnick recently is probably more realistic and achievable. We would just need to make a bigger version imo. Iowa's is pretty small because they had such little space to work with. We could probably fit two of what Iowa built in the space between the back of the endzone and Kirby and still have space left over. While we're at, make the south tunnel a bit of a cooler entrance for the band, both for their "new" pregame entrance and for when they enter and exit the stadium. There's a lot of schools that have really cool tunnel areas that create a really cool entrance for the band, and if we're renovating the horseshoe, might as well give the Marching Illini the coolest tunnel in at least the Big 10.
Another small, but worthwhile renovation to have would be to have the east and west mains mirror each other. Like Flighter mentioned, that gives us more wiggle room to add more seats in a SEZ renovation, but we could also add a big premium section on that side of the field for the same reason they would be in a SEZ renovation. It could be essentially a second Collenades Club or it it could just be more private suites, but we should make use of that space if we remove the seats rather than just leaving it empty. Removing the seats under the overhang also removes the need for the massive ramps in the East Hall opening up that space to give it similar upgrades to what have been made in the West Hall over the years.
The NEZ structure itself isn't as big of an issue as people like to make it out to be imo, but I do think it can be utilized far better than as the student section. I've liked a "family area" concept that I believe Flighter has mentioned, but I think if you really wanted to go all out, I think turning it into a standing-room-only food and drink area, similar to the setups become super popular in MLB stadiums might be a really good use. I'm thinking something similar to what Indiana has on one end. That being said, this should be the very last thing on any list of renovations. It isn't perfect how it is right now, but it's far from hurting the stadium and our gameday experience in any way.
Exactly this.
And please fix the first few rows of the east and east stands, it’s nuts that we have a tarp over them. Rip them out and push the wall back, plant shrubs there, lower the field or do whatever to fix those rows.
