BH, In a mediocre side, and on their results over the past two years the Wallabies are a mediocre international side, if you don't at least try some of the alternatives, you are compelling the team to remain mediocre. Or, if you deliberately ignore the better alternative for confected reasons, then you are arguably culpable in driving the poor performances.
IMO Cheika suffers from both afflictions.
He has a tendency to persist with failed or poorly performing players or combinations of players and apparently will not contemplate changing his ways, eg poor back row combination at present, poorly performing Nos 9 and 10, as well as certain players consistently selected last year when their contributions were very minimal at best. He has also deliberately ignored experienced in-form players on the argument they would not be starters in his side when he inconsistently has now included Steve Moore back in the squad but doesn't even put him on the bench.
Before the usual suspects just come in and accuse me of Brumbies bias, let me say that right now I would rather see Matt Philip (Force via Tahs) in place of Hanigan, Holloway (Tahs) or Timani (Rebels) in place of Dempsey, Beale (Tahs) in place of Foley, and Meakes (Force) or Hunt (Reds) in place of Beale at 12. The Brumbies who should be there are Arnold to start and Powell on the bench.
As we all know, statistics don't tell the full story, but some figures are very telling. The two poorest performing Super Rugby sides in this country have between them 15 of the 23 players in the current game day 23. That leaves just 8 spread over the three better performing sides. Something stinks in the State of Denmark.
