I would imagine just turning without moving your feet would be a football move as well. But irregardless of the rule (of course if I were a ref I would know it.
, I call that one a fumble, I thought he had control with both feet etc.
I also assume that if he stood stock still that wouldn't be a football move either, so I have to guess it's pretty subjective.
I read somewhere also however that that play was not reviewable.
