After several postponements, about 20 CCS high school playoff games happened yesterday. Several high seeds did not get home filed advantage (in a strategy to find better air quality, the games were  relocated to Morgan Hill-Gilroy, Salinas, and Pacific Grove), but at least the games happened. From my spectator perspective I could see the kids were struggling with the air quality. 
It was definitely a good decision to postpone the Stanford-Cal game.

I know the air has improved significantly since the rains last week, but I thought this article on AQI and purple air would be helpful to this discussion.

And this is a cool map that plots AQI around the world:

Here's the bay area's detailed analysis (including the temporal trend):
