I did a bit more hunting and apparently there is now an inactive list which has the players who have retired or have a season ending injury. These players create the rookie spots for the mid year draft. The long term injury list is different and has players with six weeks or more of injury and this list enables cat b rookies to be upgraded and play seniors. Accordingly I think smiths move to the LTIL and not the inactive list only creates the opportunity to upgrade either bell or wicks from cat b.
Definitely a long shot draft though I'm sure playing in the SANFL would have done him good. He might win a Brownlow given our club's talent identification on midfielders.
All we need to find is a Pendles like player. Not too much to ask, is it?
