Here is my take on this situation. If the sun is going to cause a problem for the team shooting at that basketball then it is also going to be a problem for the officials too. Glare is glare, even before the visiting coach came to me with problem and I think that I would have approached game administration with the excuse that the glare is a problem for the game officials. That makes it a neutral problem.

P.S. The glare would not have bothered me because I am blind in one eye and can't see out of the other one. 🙂
