I'm not adding to the question, you appeared to ask for further clarification with your idiotic snark.
Why should Iowa add more? What does that enable to improve?
What why do you think I was asking?
The context of what was being said was that Kinnick needs to add more seats. You asked, "Why?"
I'd like to know why you think we need to add 5000 seats that would be empty now?
Never said we should add 5,000 seats, but I can understand why it'd be a good idea.
The short answer? Lost revenue.
I think it's fairly obvious that when Iowa's teams are expected to do well or are doing well, tickets are in high demand. This year not so much, but there are factors there that weren't always there before.
Let's just use the 2009 season for example. Tickets were in extremely high demand that season and the 70k stadium couldn't meet that demand. It drove ticket prices up for people who tried to scalp tickets. That season, Iowa could have easily filled an 80k+ stadium. That's 10,000 tickets worth of lost revenue. That's $600k of lost revenue per game at $60/ticket.
It doesn't matter that there are some seasons you won't be able to fill an 80k seat stadium. What does matter is that you are able to meet the demand when it is high. A season like the 2009 season carried over into the 2010 season because expectations were high.
If you're building a new stadium or even thinking about adding seats, you don't build or add with the mindset of what you believe will fill the stadium every game. You build or add with the mindset of being able to meet demand when it's at it's highest.
You could even add 10,000 seats, drop the ticket prices by $5 (making them more affordable and attractive) and still generate more revenue than having a 70k stadium assuming they both sell out. In a season like 2009, they would have most certainly sold out as well as the early parts of 2010.
