Apparently either Samo, McCalman or Palu will miss out. And I understand the predicament, knowing Deans he could very well drop Samo. But I still don't think it is wise to drop Australia's strongest S15 number 8 when the alternatives are a guy with a lot of talent ahead of him (McCalman) and a guy who can barely stay off his crutches (Palu). For me Samo should be included plus although Deans loves the "I have a young gun team" it really can't hurt with some experience. Samo who is 35 years old and has played for the Brumbies with success compared to a starting team who haven't won one major trophy until this year. You need some experience especially as Giteau seems to have been excluded from the starting side. For me when you need a proven performer you look no further than Samo who has form on his side. The others have talent but do they have what it takes, also Samo is pretty versatile.
As for Higginbotham I totally agree with TBH's point that he wasn't all that great. He definitely isn't a Number 8.
No doubt my Reds bias is shining lights throughout this post, and not for one second am I saying McCalman isn't fit for International Rugby. He's proven that he is indeed fit for it, but he's not going to have that IT factor which Samo and Palu provide. Particularly when we could be up against Read and Spies. I reckon leaving McCalman out will only make him better. As he has a lot of talent.
