I checked whenever I typed that and you could get two tickets in seats in section FF and GG I believe (whatever is behind one of the hoops). There was another section that was down to singles that showed tickets available. I obviously didn't click on it to purchase them so maybe it was just on there as an error and I couldn't have bought them if I tried.
When I looked this weekend for tickets it was standing room only, and Rivals tweeted 5 minutes after your post that the game was sold out.
