Hello Coach, welcome to the board.

Now that you've managed to have some healthy interaction without raising anyone's hackles, why don't you take advantage of our greatest collective talent:ie, giving clear concise explanations of the rules. I suggest that your reference to the ephemeral "moving screen" indicates a lack of understanding of the concept and might be a good place to start. At the very least, you will be better prepared to school your players as to what is acceptable in terms of established screening principles.
Go ahead, ask away....
