Should the roof at University of Phoenix Stadium on Sunday Night be opened for the Nationally televised game on NBC against the Indianapolis Colts? Normally, it would be closed, however for the first ever Sunday Night Football game for the Cardinals in their new stadium, there is the possibility they would keep it open. The forecast high on Sunday is supposed to be 105, so don’t let today’s 97 fool you. So, what do you think? Should it be open. Please sound off.
