Straw man.
Foley requires a team design that caters for play making. We either run a big direct centres knowing that few holes will be created or you make up for it with another playmaker. Beale is the obvious choice though a healthy Hunt also is a possibility. This leaves Hodge compromised at 12 either through a back line without a lot of flair, or looked over as a starting 12.
How is it a straw man argument?
The same attributes at 12 that best suit Foley also suit Cooper as has been shown over the course of his test career.
This premise that somehow Cooper operates well with two big ball running centres that provide us with both the most running ability and strongest defence and that when we select Foley we have to compromise is not backed up with any sort of evidence.
When Beale has played his best rugby at 12 (which has generally been for the Waratahs or in the UK) it has been because he runs hard and takes the line on. He has played there very little at test level apart from a couple of stints off the bench.
Clearly Hunt provides a far more physical presence in defence at 12, but both of them run hard at the line when they are playing good football. I think both are better footballers than Hodge at this point in time mostly because Hodge lacks the ball playing ability of either of them.
