One sided officiating

I am not saying the Pelicans would have beaten the magic had the game been evenly called but it would have been more competitive and fun to watch. Maybe the Pelicans would have had a chance if they weren't playing the magic and the officials. How does the NBA decide on who officiates each game. How does a Orlando Florida official even get to officiate and expect to be non partial. John Conley is the official that I believe ejected the 3 players and made many unfavorable whistles in the game. He is a long time Orlando Florida resident. https://official.nba.com/wp-content/...ohn-Conley.pdf
