Gee I don't know. He would be in an assistance coaching role not a head coaching role so he couldnt be marked down that much. Being an assistant would enable him to learn what works at international level and also he would be able to learn from Chieka's mistakes without having to make the mistakes and take responsibility for them himself.
If anything having international experience should help his chances. Personally 5 years at the same province isn't as good as 3 years with a province and 2 years with international exposure.
Having said that, I applaud Larkham's decision and the comments he made regarding why he turned it down.
"I would be open to helping [if I was asked], but my focus is purely on Brumbies rugby. Anything that distracts me or detracts from that role or the program, I would be dead against it," Larkham said"

His focus is clear and anything that distracts him he pushes aside. This is great mentality of successful people.
