What if three end up level? And A beat beat B, B beat C, but C beat A. Or is that mathematically impossible?
If Eng beat Aus, but then Aus beat Wales then thats exactly your scenario.
Wales beat Eng, Eng beat Aus, Aus beat Wales
Then I guess imagine Wales beat Fiji and Eng beat Uruguay.
With no bonus points it would be:
Eng 14
Aus 13
Wales 13
But Eng are reasonably likely to get a BP against Uruguay
Wales the same for Fiji
Aus might get one for just losing to Eng, but less likely to get one for beating Wales, but Wales likely to get one for just losing to Aus
So then it would be
Eng 15
Aus 14
Wales 15
All bollocks but amusing to think about.
My predictions however are
Aus min 17 by beating Eng and Wales
Wales beat Fiji with a BP, lose to Aus with a BP so 15
England lose to Aus with a losers BP and beat Uruguay with a BP so 12
