I'd be hard-pressed to think of a more wasteful expenditure than requiring football stadiums to resemble darkened arenas for NCAA Finals. If you want an arena atmosphere, PLAY THE GAMES IN ARENAS. Instead you gouge fans to pay so they can say they were there and watch the game on a video board. The $5M Minneapolis is paying for curtains should go to smaller schools so they don't have to extort as many student fees for athletics. What is the NCAA afraid of, the sun in a foul shooter's eyes? If that is the concern, play the games after sunset. Or position the floor so sun isn't a factor. The second semifinal game and final is already at night. Plus playing the Finals in arenas would give many more cities - Columbus,hint,hint - a chance to host. Imagine a Final Four at Madison Square Garden. The final sentence sums it up: "If they don't work, we'll put everyone in sun glasses."
