Sounds like this has been part of Campbell's vision since getting here. My guess it that it ends up being similar to Missouri and Arkansas's projects. Most likely will involve bowling in the end zone just enough to make up the hillside capacities and then added suites with outdoor / indoor seating that you see getting built across the country. Then move the existing scoreboard up on top and you have yourself a totally revamped Jack Trice.
My one and only MUST is a new pressbox but I am guessing that will not be part of this project since so much money will go into the football offices / facilities below and behind the stands.
Missouri's new facility is $100 million for new coaches offices and football facility outside the South end of the stadium while adding luxury suites which will reduce stadium capacity. The potential problem with the plan is the bonds were sold predicated on increased attendance when in fact attendance for Missouri football is significantly decreased. Final 3 home games vs Utah, Florida and Tennessee averaged 49,000. With the school's bond rating already having been downgraded due to declining enrollment - several newly built dorms are sitting empty - if these bonds don't produce the anticipated revenue it could further damage the school's bond rating.
Missouri and Iowa State are programs headed in different directions.
