Here.. For me.. This seasson the biggest ref mistake was in the game Toronto - Atlanta, when the game wining layup of TJ Ford was uncouted..
Here watch this video.. http://www.youtube.com/watch?v=Nt1jHSh8RR4
As you can see the clock was on 0.5 before the imbound. And when it stared to count, there was a space between the ball and Ford's hands.. It was 0.4 in this time..
And as the final result show that in the NBA.. a 0.1 mistake can be the key for Winning/loosing a game
