The only confirmed game I found is Knicks @ Nets opening night...but that wouldn't work as the Heat are probably going to get their rings opening night. This past season, there was 3 opening night games and 1 of those was on league pass.
My guess for opening night is
Celtics @ Heat for the salty looks of KG
Lakers @ OKC (because the Spurs don't matter until April anyway and I've accepted that!)
if it's a 3rd game
I'd pick Hornets @ Warriors or Wolves @ Blazers
Tony Allen tweeted the Grizz were playing the Clippers.
