I know it will cost money but I am sure a pricing model can be found to increase overall revenue by filling 20,000 more seats per game.
In reality BYU dropped the ball on stadium expansion. Other schools add 5-10k seats every several years. You don't wait 3 decades and then wonder how an extra 30k seate will be filled.
In 90 should have added 10 k. After 96 another 5K and in 07-08 add 5k more. We would already be at 80000 capacity and the local fan base would have been conditioned to understand if you are a local fan you watch the game in person.
