My reading of what Holbrook said wasn't that Wilkin won't be in the 17, but that he will be on the sub's bench a lot more, rather than playing the full 80 minutes.
I'm a Wilkin fan, but I do accept that his time is drawing to a close. He's been a superb servant to the club, and although he was perhaps most effective in his early years as a second-row, I think the important contribution he made as a tactical kicker and ball handler, when we've had no other options, is too often underestimated by fans.
With our current relative wealth of halfback talent, there's no place left for him there now, and second-row is a job for a bigger, faster and younger man now.
