I will say, the improvements to the lower west concourse and underbelly have been welcomed and very nice. The problem with the lower west side is it's age and how that relates to the seating. I always thought they could have divided each section in half and created new walkways to decrease the length of the rows (which again, are the longest in the SEC measured in google earth), especially with that area being full of mostly season ticketed alumni and fans, but they have done absolutely nothing over the years. It's the most uncomfortable area of the stadium to sit in.
It really needs to be demolished as you said, but that would be a major major undertaking that would require lots of time and funding. If there was a way to chairback the entire lower west side, that might be the best option.
