Your blokes will need to score early and often to take the wind out of the Pumas. I wouldnt want Aus to be in an arm wrestle ie < 3 ahead with 15 to go against them.
If the Wobs take it up early against the Argies - it may result in a contest of attrition, and a blunt force trauma approach considering the weather may benefit the most accurate boot.
I would suggest as another option the opposite, absorb the early onslaught with defense and overwhelm as they tire and punish them as errors increase.. their running rugby only lasted 1 half and a better Irish would have put them away.
It relies on the tried and tested approach seen throughout the TRC of bench play which could account for the Argy new enterprising play with the superior productivity of the reserves. Although, this is tempered by a significantly lower error margin and addressing the sudden onset of hesitancy that arrested the killer touch needed against the Scots. Either way, Wobs cant afford or carry a wayward Foley.
