Quote: Andy Gilder "Hardaker had both arms around Amor at the time, so was in control of how he took him to ground.
Brough had one hand on Hardaker's shirt IIRC at the point he wrapped his legs. He had no control over how Hardaker went to ground, which was exacerbated by Kopczak's reckless shoulder charge knocking Hardaker backwards.
It's a bit like comparing Sneyd on McGuire with Issac Luke on Chase. Similar actions, but some distinctions to the intent/care taken by the tackler.'"
And the official notes to the laws make exactly that distinction (when referring to throws etc)...
"It is permissible for a tackler to bring a player in possession of the ball to the ground by pulling him over the outstretched leg provided he is holding the player with both arms before there is any contact with the leg."
