Oh yes there is. First, you take the side that gives you the advantage in the 4th quarter if you have the chance. Second, it's their home field. They should have a specific set of plays designed to neutralize the effect of the sun. They should know from where the QB can throw to a WR and take the sun out of the play and design plays for that. Roll the QB out so he is throwing from a position where the sun is not directly at his back. Do something to limit the impact. It is beyond my comprehension that a pro football coach would allow the design of his stadium to negatively impact his team without even trying to do something about it. It could become a huge advantage if you are prepared for it when other teams are not.
