I see what your saying but watch the video at about 43 sec..while grant is sitting down you cannot see the hangers over his head..They only come into frame when he stands up..Grant was sitting down when the hanger was thrown a second time so what would make you think the hangers were in the frame at that point?? They probably had the exact same angle of when he was sitting at 43 sec no hangers in view possibly not even to pick it up while it was thrown..Again nothing conclusive..
