The way I see this going is by the description given, movement is legal, any contact initiated by the screener while moving = illegal screen or a block. (terminaology may be the hang up)

My belief that it doesn't exist refers to the fact that it is NOT a violation. I am simply refering to the fact that the coaches are looking for a violation (moving screen) when there is none. There is no violation (moving screen) when players simply move in the same direction. Therefore, in my book - it doesn't exist. Sorry for the confusion.

Unfortuanately, in your book (rulebook, that is), it does exist. :)

I totally understand your point, and I agree that it's not a foul and coaches misuse the phrase. But moving screens are described in the rulebook. That's my only point. And I'll stop annoying you now. :)

Wow, so we wasted all of that energy to get to the point that we all actually agree?? And here I thought popcorn was in order.

Movement while setting the screen is legal, insofar as the screener doesn't initiate contact. The term "moving screen" does not exist in the section on violations or fouls, since it is perfectly legal to move while setting a screen. Once the contact occurs, then there is an "illegal screen" which I have seen called as a block or push.

The rulebook does refer to a moving screen, but only in terms of what was posted previously.

No matter what terminology you use or what you call it, CALL IT RIGHT!!
