When I see critiques of the concourses or bathroom wait lines, I wonder if the complainers have ever been to any other older stadium ever? I don't think I've ever been to a sold out stadium, old or new, without those issues. We won't see improvements on any of that without a massive renovation to the stadium - certainly nothing that could be solved in the off-season.
I haven't been to a game at MS in a couple years as I live a flight away, but I was surprised the last time I went to a game that they stopped doing flags/William Tell between the 3rd and 4th. I don't think it answers the stadium song question, but I did think it was a great 3rd to 4th quarter transition that the whole stadium participated in. From this thread, it sounds like they've continued to shun that tradition, unfortunately. I have to say, I don't think I've seen a good stadium song suggestion in this thread. Most feel like suggestions from Grandpa Hoosier.
From watching on TV, I have been really disappointed in the decision to display the most bare bones version of MS. All the on field wall graphics are gone, and all the exterior banners are gone. The exterior banners did need replaced as they had faded to pink, but we should be able to put fresh graphics up everywhere each year. Really a tiny expense for a great visual impact. MS looks so institutional without it. When other schools have gone all out on the in stadium production, with light shows and dramatic presentations, it's disappointing that IU is still showing up like IU, especially considering the great year the team is having. Our production level hasn't changed since the early aughts.
I'll never let a stadium discussion pass without a critique of our matchbox press box. I know they surveyed fans this year about additional seating options. Now is the time to move. IUFB has not had this kind of momentum in our lifetimes. Hope the AD seizes it and moves IU into the current century. All around, gotta do better.
