I watched the play over & over. In fact I just watched it again on the ACC website. Yes Giles was moving, but no there didn't look to be any contact. He made Wilbekin run wide almost on the baseline. So you have to ask yourself as the baseline official--Was the screen moving or was their contact? Pick and rolls are perfect examples of "moving screens" and Stockton & Malone made the NBA HOF doing that. They are perfectly legal. What makes a screen illegal is illegal contact--screens by their nature are going to create contact because that is what they do. If a defense pushes thru the screener, the foul is on the defense. If the defense just wallops the screener because he doesn't see him [blind screen], bounces off but doesn't push thru, no foul--incidental contact. However if the screener sets if but moves an elbow or knee into the defender to knock them off their path, thus creating the illegal contact, then it is a foul.
Personally I would have liked to have seen McClinton tried on Kennard late in the 2nd half because obviously what we were doing with our guards wasn't working!
as someone else said, it would have been better if Wilby had run into Giles leg and got caught up as Giles was moving - the official would almost have had to call something...
