High low action by VCU against a zone defense

In this play, we see Jamie Skeen working hard to post up on the right block. Frank Hassell is playing solid three quarter defense and not letting an entry pass be made to Skeen. VCU then runs some natural high low motion and it results in Skeen getting the ball in a position to score, when it looked unlikely he was going to at first.

You can see the defense of Hassell below. The one critique I have is that he be on the opposite side of Skeen, since his help is going to come from the middle and he needs to be able to stop any baseline drive. By playing on the high side of Skeen, he is leaving the baseline open for the dribble drive or Skeen to make a post move to the baseline if the entry pass is made.
