Yep... plus the days are getting shorter right now, so sunset will occur at 5:08pm on Saturday... with the sides of the stadium cutting off the sunlight from hitting the field WELL before that - probably as early as 3:30 or 4pm.
I watched the game on the sec site yesterday at work (i was at the game so i wanted to hear the the cbs stuff -- they weren't that bad). CBS replayed that announcement when they came back from the 4th Quarter timeout break. They seemed to love the announcement.
