Controversial calls are almost a guarantee to happen, no matter the sport or competition level. The reason it's pretty much a guarantee is because all referees are human, and humans make mistakes. Something also we should note is that if something is viewed as controversial, there will almost certainly be biases playing a part.
Many people nitpicking all these things to make the point that the game was rigged all have a reason with some sort of bias for the Lynx or against the Liberty. Otherwise they wouldn't really care or be complaining in the first place.
I can understand the frustration that the commissioner of the league was wearing a dress that resembled New York, and that seems extremely unprofessional for a person of her hierarchy. But, I think it would be a slight exaggeration to automatically come to the conclusion that the game was rigged based on her dress.
One call or one dress doesn't decide a game. Each team has 40 minutes of regulation play to win the game. Controversy is a staple of sports that shouldn't be looked at as rigged if it didn't go in favor of your bias. There is not enough sufficient and clear evidence to support that this game was absolutely rigged.
