To come through the ranks at the club? I know defenders tend to be a bit older when they come through, particularly CH position but I'm struggling to think of the last defender to get a run of games who came through the ranks? George McCartney?
And before George we would probably have to go back to Dicky Ord, Shaun Elliot or Rob Hindmarch if my memory serves me well.
Shaun started off in midfield with Arnot and Rowell just after Xmas, one of the most exciting introductions of youth into the team I can remember.
