Howler Mokey sez: "He wasnt set"

[Hawks Coach]

In most cases when charges are drawn and called, the defender moves in such a way that he must get set in order to draw a charge. The first is obviously the airborne shooter example. Another is a player who gains a step on the player he is guarding and then jumps into the path of the dribbler. A third would be jumping into a trap that is being set directly in the offensive player's line of motion.

While it is clearly a charge to change course into a moving defender who has established legal guarding position, this is the least frequently called charge. So while it is a rule and can be enforced, it is enough out of the norm of what is really called in games that most coaches, players, and fans are used to seeing charging called only when a defender is truly set. And some refs will only call it that way as well - so start by informing them before criticizing the coaches. So there is good reason that you hear this.
