Much to my surprise, the StubHub Center has fixed all the issues. I could immediately tell by the even light across the field (see below). They even fixed the angle of the lights, so that when you are shooting across the field you are not getting glare into the lens. Thank you StubHub! Here's some samples from the game.

Ps. - for those who have shot at the StubHub/Home Depot Center, as you are walking out the tunnel to the field, to your left they have built a nice lounge. Looks pretty sweet!
