Sure the stadium could be even better then it is now, but it's improved greatly and the one thing about it that boatloads of college stadiums still can't say is that things like restrooms and concessions are all less then 20 years old, and not skank ass rat holes like in many college stadiums.
My wants:
A mini WSC on the East Side, anything on the scale of WSC on the East is a total waste of money, but when they renovate the East club level and suites if they want to build a mini WSC to add additional club spaces and amenities that would be cool. Nearly all stadiums have somewhat unappealing risers and beams showing on their upper level, but a mini WSC that runs from say the 35 to the 35 would break that up substantially.
I would prefer that they just went ahead and mirrored the North Video-boards on the South creating the best overall AV experience in college football.
Renovate Bramlage extensively and in the process create a club that overlooks the stadium with maybe 1200-1500 high end outdoor seats that are connected to the Bramlage Club, and then redo the entirety of concessions and restrooms in the North endzone. As part of the Bramlage remodel move the entirety of Athletic administration back to Bramlage and back out of new Vanier.
Obviously the limestone wall.
In la-la land I would truly love to see them blow up the entirety of Brandenbury, RV Christian Track, and the large indoor facility and start over. In place of Brandenbury build a substantial complex that houses baseball, soccer, and track and field that is all encompassing with dedicated dressing rooms for each, a strength center, sports medicine and admin offices for all sports housed within. Adjust the placement of the outdoor track so as to allow both a new indoor track and new indoor facility supporting baseball and soccer to be built. Let's be honest, it's time for the Ag School and athletics to strike a deal and for the Ag school to sell athletics the land right across the street from Vanier so a new indoor/outdoor football practice complex can be built. There's acres and acres of land for Ag to play with nearby and all over the state, and that end of campus is rapidly being assimilated into the campus core.
