Off the top of my head, I'd say 4, I think. Macrae, Bont, T. Boyd and Stringer
Boyd wasn't drafted by the Dogs though.
If you include Boyd for the Dogs (fair enough), then for this season just gone Geelong had 4 (Selwood, Dangerfield, Rohan, and Henderson). Higgins was pick 11 and Cameron probably would have gone fairly early.
