Even an 85 per cent fit Smith would do the early business for the Wallabies to help absorb the Lions and take some of the sting out of their play before unleashing Hooper.
Smith might have hurt his knee a while back but the man has warrior blood flowing through his teak frame, he understands the methods of heavy battles rather than lighter skirmishes, he is as born to test rugby as Richie McCaw.
New Zealand has tut-tutted about Sam Cane's production in the absence of McCaw. The difference is noticeable. No fault of Cane, he is a rising work in progress while McCaw is readying for his 13th season of international rugby.
Hooper has played 14 tests and Gill nine as they make their way in the maelstrom of international rugby.
Smith has seen most of it before and certainly experienced just about everything that can happen in the test arena. It's all about knowledge and expertise.
The Wallaby frontrow is accruing that with tighthead Ben Alexander ticking off his 50th test tomorrow to become only the fourth Australian prop to reach that milestone. He joins loosehead Benn Robinson, Al Baxter and Reds coach Ewen Mckenzie in that select group.
Alexander dismisses talk about perceived Wallaby weakness in the scrums as a hoary old topic.
