Correct. Players who have previously been on an AFL list have this option. First year draftees do not.
Ball went to Collingwood via the ND, using the exact pick which St Kilda refused to accept in the trade.
There have been very few players/trades which broke down so completely that the player ended up leaving via the ND or PSD. Camporeale, Stevens, Martin, Ball, Pond Scum. The fact that we can recall them all so clearly is an indicator of just how rare these occurrences really are, and just how many end up being traded completely amicably without needing to take the "nuclear option".
Remove Tippett, we were accepting that s**t deal.
