Very simple math he'd be losing a boatload of money by doing that. You're selling those tickets for $175 already with 3,500 students at $125/each for $2,500 seats.JP showed his hand when he tweeted his displeasure with the students a month or so ago. Last night had to be the "straw that broke the camel's back." Top 25 matchup, gorgeous day, 6:00 start... no reason for students not to be there. It's not worth selling all those tickets to fill up for the Iowa and Kansas game. Take the upper section student section away and sell them as $125 season tickets.
And the student fees are a big deal with the University working to keep tuition as low as possible. There's a few million dollars there that's "free" money for the AD. You don't bite the hand that feeds by restricting your #2 offering and giving them reason to either keep the student fee the same or decrease it.
If a move is made it won't be for financial reasons....it'll be for perception reasons because making it make financial sense is going to be very difficult.
