Angus/Rennie definitely found a way to depower our scrum, via the media and direct contact with World Rugby.
The tactic backfired to some extent IE we still won the match...
The Georgian ref, Nika Amashukeli, comes from a country with a scrummaging culture. I don't think he'll be easily influenced or conned.
In addition to that he's going to be officiating in front of 95 000 rabid South African fans... that alone should help us garner our fair share of the 50/50s...
Tough assignment for him, in all honesty.
The ref and how he interprets the breakdowns and scrums will likely have a fundamental bearing on the outcome of the test.
