It is actually illegal. A ref pinned saia for it. No arms in the tackle. It's a shoulder to the leg.
TPN's technique has been observed by dozens of refs over five years of international and provincial play, and no one has penalised him. If he used no arms, then fine. But it would appear that he does use his arms, or else, arguably, someone with a whistle would have noticed.
