First and foremost, Tommy was absolutely hilarious during the end of that game
Second - the offensive foul on Pierce was the worst call of the overtime session. You can't call that there.
The Stiemer offensive foul was terrible too, but I can see why it was called since his elbow was up by Smith's face. The worst call of the game also went against Stiemer, when he cleanly blocked Teague and the opposite side official, blind to the shot, called the foul.
The KG foul is a little tougher since you can't really see from the angle whether KG locked the arm or Teague was pushing him. I'll give the benefit to the refs on that one.
But the game overall was horrendously officiated. Next to politicians, NBA refs are the most incompetent and corrupt people to hold jobs of wealth and power in our country.
