Geez, Ennis talks nonsense. Yeah, they may have got the Bostock call wrong, but it was a split second and arguably the touchies call, given the touchie is 5 meters away and the ref is 20-30 meters away. That happens.
But the Kini sin bin was absolutely correct. The bloke came in after the tackle was complete to push the Dolphin out to kill the play, knowing full well the Titans were struggling to get back...if Kini had just held on and refused to let the player up, it would have been a bin as well.
It's actually more annoying (and bad for the game imo) when teams earn the right to a quick play the ball either through a dominant carry, tackle bust or line break, and the ref gives too much leeway to the defending team, which has lost that contest.
