It's amazing how a T can change the game

Sometimes there's nothing like a T to whack some sense into a coach and get him to stop officiating and start coaching.

Well said, this is why i believe that a T is a tool that must be used more often not just threatened. I've found that the majority of coaches after one, never do anything that would earn them a second, and it makes it much easier for the officials and the players when the coaches shut up.
That's why I use the technical foul more often then most officials.
