The last time England were in Adelaide for an Ashes test, Graeme Swann, during pre-match nets, passed on a few words of advice to a young offspinner who was combining trying to make his way in the game with earning a living tending the turf at the Adelaide Oval.
It is a very different surface Swann will bowl on this week when the second test begins and it is also a very different Nathan Lyon who will be pulling on a baggy green cap rather than the overalls of a groundsman.
The teams are still to assemble in South Australia but already there is a swirl of speculation over the surface that lies in store. Lyon knows the ground all too well but will have no more knowledge of the pitch on which he and Swann will bowl than his fellow offspinner as the contest will be played on a drop-in wicket.
For one and all here is a known unknown. Sheffield Shield games in Adelaide this season have been on slow, steady surfaces, fuelling talk England might field two spinners. Australia won't. They will field one front-line spinner and at last Lyon can be certain the job will be his.
Amid all the fire and brimstone in Brisbane, Lyon's quietly effective performance offered as much encouragement to Michael Clarke and Australia's brains trust as any. Clarke and the selectors have seemed slow to be convinced by Lyon, all too ready to look elsewhere, wanting a wild card rather than the steadiness of an unprepossessing offspinner.
