One of Utah's Pac-12 foes, Arizona State, has announced a "tentative" plan that would turn Sun Devil Stadium into something that looks like a cross between a soccer venue and an enormous spaceship. According to the university, the revamping "would create a shade canopy over the stadium that will allow the passage of natural light and the passage of air into the stadium."
Why go to all that trouble? Why reduce the capacity of your stadium from 71,000 to "between 55,000 and 65,000 seats"? Why not just keep playing night games to avoid the torrid Arizona heat?
Because the the canopy is designed to allow the Sun Devils "to play day games earlier in the year to accommodate Pac-12 Network obligations."
