Tropical Storm remnants expected to hit SoCal Sunday (Update: Game will go as scheduled)

So with this statement, it seems you're confirming that it was okay to continue with going ahead and play the game. The league and stadium personnel checked with the NWS, radar, and updated projections and determined it was low risk because the storm was severely weakened and rain projections were 1-2 inches. Especially considering that few people were going to turn out anyway given it was a preseason game combined with the rainy weather. We've seen much worse with El Nino storms and santa Ana winds.
People can still get hurt or in car wrecks and it was unnecessary to do so because it was a low-importance preseason game. The fact that game wasnt well-attended speaks to most fans didnt take any chances or risks driving in bad weather. Sure, it was a pre-season game and they usually attract low attendence anyway, but its difficult to argue that the game wouldn't had larger attendence if it werent for L.A. having its first TS/hurricane in 84 years.
