[Back In The Saddle]

After watching the video a few times...

The defender clearly establishes LGP before the offensive player goes airborne. He then moves slightly laterally and backward to maintain it. But his movement does not appear to change the the fundamental relationship between them. In other words, he was "there" before the offensive player went airborne, and what little movement he made did not substantially alter how the impending contact would occur. Certainly we prefer the defender be "set" on this play, but the defender is allowed to move to maintain LGP.

The offensive player is moving from the elbow directly to the basket, and the defender is directly in the path. The contact is squarely in the chest, and is caused by the offensive player. So, if I have a call on this, it's going to be PC.

However, from the video I can't tell how significant the contact really is. Nor do we have the context to know how earlier similar plays have been called/no-called.
