The foul is immaterial and that's what Owens should have ruled. Refs make/leave calls all the time based on materiality and this case was no different. If the infringement was a case of dangerous foul play, then yes, the play would be called back, but there is no case for calling back the play here.
Refs make obstruction/offside calls based on materiality (whether it affected the run of play) so from my perspective, it was a very controversial call because for me, Savea had no chance of catching Speight at that point. Owens made a mistake in not taking that into account and Veldsman was equally as accountable for not pointing it out.
Exact same thing happened to me in a league in Canada and the guy was given a 4 game ban. The force of the kick snapped my teeth and lodged them in the roof of my mouth and the fallout from the lack of punishment resulted in the league disintegrating.
I'm not sure what the fuss is - locking onto the ball and holding the player up has been a tactic for years. It is a great way to turnover ball and it forces the attacking player to be conscious of their body position in the tackle. »
