I think Barritt is one of a number of players that your point could be applied to. I remember Jeff Wilson saying that a difference between rugby today and rugby twenty years ago is that back then players ran at space and tried to avoid tackles; now they run at players and try to win the collision.
Until reading your comment I actually hadn't realised what had happened. The guy is obstructing Flowers a bit, but as you said, on 1.18 Flowers appears to clothesline him or strike him in some way to remove the obstacle. I thought he had just pushed him, which would have been fine, but on closer inspection that's not the case at all. »
It's not suspicious in the slightest. The IRB rankings are extremely transparent and a full explanation can be found on the website. If Argentina went up two places in the rankings it's because the two teams ahead of them weren't very far ahead of them to begin with, and beating a team as highly ranked as Australia gave an abnormally large boost to their ranking points.
Do you not think he took it a bit far by actually interfering with the play? One thing is going on at a break in play and running around a bit, but another is actually interfering with play and putting one team at a disadvantage.
