He came around the side to kick the ball though... clear penalty.
Re-watched. He came through the gate (and was the only Waratah player), then kind of disengaged for a second and came a bit from the side just before he kicked it. Close thing, but penalty OK. Yellow? Not so sure as he is completely entitled to kick the ball
if he is part of the ruck, despite Rohan Hoffman's brain-fucked version of the laws. Mark what he said - "Can't play the ball with feet in a ruck" - I would not say it was a clear cut cynical action at all after reviewing. Watch the whole event, not just the last second.
That aside, the Tahs were a soft pastiche of a rugby team who deserve all opprobrium heaped upon their sorry, weak, rope-grasping asses. How they manage to make a 4 tries a-piece game look like a rout is beyond me, but they did. Not even close to a pass mark. Weak. As. Piss.
