well I'm no Rugby wiz at all, but I love scrums and I've learned the basic laws and possible penalty situations. Stay bound, don't pull guy down, support your own weight, no hands or knees on ground, angling, pressure upwards head popping up, collapsing scrum intentionally, position of hands on your opposite prop...that sort of thing. I mean it's not rocket science, the hardest thing is classically if a scrum collapses, how the fk do you know which guy did it ? I've sometimes replayed the same scrum like 10x, slowed down on VLC media player, focused all my concentration and still came out empty at times. I agree with what some pundit once said "only the props themselves know, really...". Because you'll see a prop shaking his head or wtvr but he could very well be dishonest and vexed, so that's no indication.
anyways here about Pumas and Boks,
stormer, I've read your comments and looked at the vid. at the same time: I reckon you're being pedantic and unfair sometimes, for e.g. the 1st scrum yes Herrera comes up but Walsh is on Ayerza's side. Those calls happen all the time during scrums, and the pressure is generally coming from the Pumas rather than the Boks.
Of course Ayerza's bound on the 2nd scrum.
To me this is clearly the Pumas have the better scrum, if not for a call or two that could've gone both ways, and they've shown it in over two full matches now.
And I don't mean to twist the knife in the wound for Bok fans, but for this thread's sake the stats are incredibly one-dimensional for the game:

At the end of the day the Boks won, and that's all that matters really for them. For the Pumas, they've at least got the moral victory, and no matter what ppl say, it's better to show you can really play than take a 40-point pounding, so yes, this is huge positive for Argentine ovalness.
