See post #732. It is only my guess, but I believe the main reason would be to protect from direct sun/glare/heat gain. It may seem funny, but there is a cartoon of ants under a magnifying glass floating around that has some truth to it. It is not that light would be collected and focused into a "laser" beam to burn people, but the temperature fluctuations brought about by the direct sun and it's position changes can present some pretty difficult HVAC challenges in a large space like a stadium. In addition and probably more importantly, the sun in people's eyes (players in particular) and the shadows created by direct sun can also create all kinds of havoc. Baseball stadiums are always oriented so that the batter faces north so that he can have the best chance to see the 95 mph fastball coming at him for example (also why the centerfield seats are often tarped off with a dark color and the wall markings are black instead of white). This is less a concern in football, and less than that if the field moves east/west as ours does, but if controlling that light makes the LED light show more feasible, allows less A/C expense because of a controlled heat gain, and in general makes the fan experience a more pleasant one in terms of seeing the field and being comfortable, then you do it.
