The final paragraph of this article reads ...

It is just strange that in three different Sevens matches, three different referees played a stand-up tackle as a tackle - pre-1977 stuff - when no part of the held player, other than his feet, made contact with the ground.

Does anyone know of, or have a clip, of these 3 examples ? Or have insight to any change of interpretation arriving ?
