The 10:30 ET NBA games are both in the Pacific Time Zone, so they are 7:30 local, and I understand having regular season games that late, but the playoffs are supposed to be attracting a national viewing audience, and you aren't getting very many people in the Eastern/Central Time Zones (which is like 3/4 of the population) watching a game that late. Especially on a Saturday, when you have all freaking day to show games.
Yes, I get that 8:30 local time is irritating for Hawks/Wild fans, but the game before theirs is in the Eastern Time Zone so if they don't want the games overlapping then 9:30 Eastern is really the earliest they can have the second game.
