You have an issue with human nature then. Fans have for a long time wanted perfect accuracy in professional sports. Controversy like you just stated have been a product of a loose or tight strike zone in major league baseball, spotting the ball in football, foul calls in basketball. That's the human element. Be disgusted all you want, but the games aren't played by robot machines and they aren't officiated by robot machines.
Tough calls are made. Even bad calls are made. That's the nature of the human element. That's why some people are so adamant about instant replay one way or the other. It both aids and attacks the human element. We could just play all these games in computer simulation.
Your problem isn't with the calls in the fourth quarter being wrong. If you go back and watch the fourth quarter, I bet you that almost all of the calls were good calls and very few were even questionable. Your problem is with consistency. Sorry, but it's just too hard. And it's not like it's the same exact official calling every single call. Consistency is tough to accomplish when you have one official, let alone three different officials who see things differently. Watch an entire game, and each official might call things different when it's their call and they see the same exact play. Part of the human element. Part of the game.
The calls were not wrong (again for the most part). They were discretionary. Did they call it tighter in the fourth quarter? Sure. Were they consistent? Nope. In all reality and honesty, they never are, not for any game, playoffs, regular season, whatever. It's a myth to think a crew of three officials can be completely consistent throughout 48 minutes. They simply won't be. You're going to have a handful of calls you argue with no matter what.
If you're honest with yourself, this is just a matter of you deep inside hating seeing a team you despise win. That's my opinion anyway. But I don't blame you. It's only human nature.
