This is a very valid point for that sideline, and I am sympathetic to the idea that you just can't replicate how cool it was to have the Krush literally standing on the court. I suppose we could have done a setup like Duke where the TV camera does not look at the benches, and we could have tried to keep the Krush on the floor opposite the benches like they used to be. However, whatever we lost on the non-TV sideline, I would argue this is a pretty huge improvement on the opposite side. At least IMO, the setup on TV is vastly superior ... it used to drive me nuts to have the national audience see the giant unused space before A Section and then a bunch of unused gray seats.
Also, does anyone know how many Krush students are around the court now? I would honestly be shocked if it was fewer than before the renovation.
I'm sympathetic to the idea of looking back at the Glory Days with rose-tinted glasses, and there were certainly probably random games in that era where the Hall seemed dead. However, there are a lot of games available on YouTube from many years. I would argue there is pretty clear evidence that our home court atmosphere, specifically the Krush, has objectively declined. The only game in this great 2020-2026 stretch where I thought to myself, "Wow, this place is rocking like the mid-2000s!" was the 2021-22 home loss to #11 Arizona. Kind of hilariously, I figured out that was a Krush "alumni" game.
The parts of your post I will agree with is that (A) Illini fans are certainly some of the best around in terms of our loyalty and passion for the program, and (B) SFC indeed can still get really loud and be very intimidating. However, I definitely think our consistency has slipped mightily.
