Coach Steve Hansen agreed with that assessment and believed the first five-eight would produce a display worthy of the black jersey, whether in the run-on XV or off the bench.
"We've pretty much made a decision but there's no point telling Stuart Lancaster that yet," Hansen said. "[Cruden's] in a side who, at the moment, are having their issues and he's the captain of that side, so he's probably come back in trying too hard. But I think that 80 minutes on Saturday would have done a world of good and we'll see how he comes through the week."
Fitness was not an issue for Cruden against the Waratahs, having remained in shape while resting a broken thumb, but execution was an issue. He missed touch from a couple of penalties and he was short of his usual influence in attack.
But rather than reflect on that, the 25-year-old need only cast his mind back to a certain sideline conversion in Dublin if he's short of any self-belief.
"I just have to look back at the last moments I had in the All Blacks jersey and get a lot of confidence and comfort from that. If given the opportunity to wear that No 10 jersey, I'll jump at the chance and give it a great crack."
And if not, he still has his part to play in the squad.
"It's a really healthy competition. Whoever gets the job, the other guys have a massive role to play in supporting that guy and doing everything we can to get the right result."
