Movement during a screen is never illegal. So when you here some fans talk about "moving screen," they are clueless. It is always perfectly legal for a screener to move. What is illegal is the contact. And to be honest with you, unless the contact puts the defender at a great advantage, do not expect it to be called. With 10 players in constant movement, if officials called every time these players ran into each other, we would never stop blowing the whistle.

I did not see the play that you talk about, but unless it directly affected the play, or the contact was purposely rough, I am sure that the officials was not going to try to call it in that situation. But again, officials do mess up sometimes. We are only human.
