It would take a season plus an off-season for him to even get close to peak fitness - at his age, it takes a very long time indeed to get back to peak fitness after even one season out.
Yes, I appreciate Vickerman's value as a mentor, but I wouldn't expect anything of him on the field. A step above a dud/failure may still be hovering at the failure-level.
Noddy; Vickerman just wasn't out muscled vs the Poms at the last RWC, he was outplayed (and out of form) and he knew it - and he gave away absolutely stupid penalties to boot. It was one of the worst performances from an Aus second row ever in a RWC. To me it just showed that he hadn't had enough playing time to get back to the level required - didn't he miss the entire S14 that year? fatprop; yeah, you can say that the entire pack was outplayed in that game and you would probably be right, but some contributed a lot less than others, and Vickerman stunk, with the tragedy being a fully fit and in form Vickerman might have won us the game. The point being, yes Vickerman was a great player, but I think everyone is expecting way too much of him, should he return.
