To add to my thoughts....bias is one of the reasons I don't watch the NBA. Bias is one reason I stopped watching Braves baseball back in the day. How can we ever know that Jordan was the best basketball player ever, if he got every call? Call the game the same way, for everyone, all the time during a game. That's the only fair way to play a game. If two people are playing against each other, but one is playing by rules that give her an advantage, are they even playing the same game? I have no idea why anyone would like bias. Take the "let the players decide" idiocy of the NFL interference rules. By not calling interference, because you want the play to rule, you are actually not doing so. If it is interference, it is interference. By not calling the penalty, you are not letting the playerd decide the game, you are letting one player play by different rules, and making it an unfair contest. It's logical laziness to say you are letting the players decide the outcome of that play.
Have I mentioned how much I hate unfair application of rules in sports and other competitions? There is no good argument for the bad application of rules. None.*
