re: New Orleans regional and 2012 Final Four

I thought the raised floor in the huge stadiums were a new thing?

I know they've had a final four in New Orleans before, but I assumed it was set-up like the final fours in Atlanta that I've been to where they only used one endzone and had the curtain up with the risers on one sideline

but with the raised floor in the middle, they're able to sell out the entire stadium
