"Pivot-Cheek"

[Ref in PA]

In NFHS, a player on the floor is not allowed to roll. The question I need an answer for is: "Is the person rolling from cheek to cheek?" When a player is standing up, the pivot is usually done on the ball of the foot. On occaision, I have seen players pivot on the heel, then on the ball of the foot, then on the heel again. In essense, the original pivot spot was moved because of the heel/toe action. I have called a travel in those cases - mostly under the explanation of dragging the pivot foot. So, in the case above, if I determine movement from the pivot area, for whatever reason, I would call a travel violation. If the player more or less stays in the same spot, I would allow the pivot action.
