What Do You Have Here??

[NCHSAA]

Ponder this situation and post what you think the appropriate call would be:

A1 and B5 are going for a rebound under the basket. The ball is not secured and bounces to the corner of the court where both players continue to go after it. The ball is eventually picked up by another Team A player and is moved up the court to their frontcourt. Meanwhile during the struggle for the loose ball both A1 and B5 go down. The official stays with both players and sees B5 extend his leg toward A1 as both are on the ground. It was not a full kick, but was an obvious extension and B5 was looking right at A1 when it happened. Contact was made on the torso/lower side of A1. The official whistles an Intentional Foul on B5. His ruling was that he knew he missed something that happened on the rebounding action against B5 and felt an Intentional was the right call. It didn't toss B5, but sent a message that this kind of play would not be tolerated. An observer however stated that an unsporting Technical or Flagrant Personal should have been called and that he indeed missed an elbow in the back by A1 toward B5 during rebounding action.
