Sloppy, lousy technique. Not uncommon on the 727. New FO's would be told the ususal B.S. "don't land at idle because the plane will fall out of the sky."
Almost every 727 landing was at idle.
727 flaps 30 is less tricky than a 737NG with flaps 40. I'd estimate a 727 flaps 30 would be like landing a 737NG with flaps 35.
