Still praying this is how it went down:
GWS want assurance from us we won't bid on Green before trading for pick 4. We say "ok we won't bid, but you gotta promise not to pick Young or Sydney's preferred player, and Sydney, you gotta promise not to pick Young or bid on Green." A trade of words if you will.
We then go to Freo who want to trade for 8 and say "alright we'll only do the trade if you promise not to pick Young or Carlton's player, and Carlton in return also can't pick Young".
Maybe we got Adelaide involved as well. And BAM Young gets to pick 10.... I can dream.
