There's no need for the personal attacks.
There's a six day overlap period between when RFA finishes and whe the AFL trade period commences. Geelong could easily hold off it offer to Patrick on the first three days of the RFA period. Adelaide CAN'T match until it knows what Geelong intends on offering Patrick. Geelong, as part of its overall list management strategy, could have set aside its draft picks for this year for other trade targets which it has already discussed and agreed upon with other suitors.
It's a very real possibility that Geelong will swap its pick #9 for two picks in the early 20s and use both of those picks for Lachie Henderson and, say a Zac Smith. What does Adelaide do if, by the time it comes around to Geelong offering Danger an offer, there's nothing left for Adelaide to be worth risking the loss of a first round compensation draft pick for? Does Adelaide a) match the deal anyway, knowing that they lose a first round draft pick, or b) accept pick #14 in compensation and move on?
If its the former, and as you suggest a "normal trade situation" ensues, what does Adelaide do? Trade Danger somewhere that he doesn't want to go? If he's nominated Geelong and Geelong only - which he will, then he WILL NOT be playing anywhere else. And if Adelaide's demands are too crippling, Geelong walk and Patrick ends up in the PSD where no club will take him. What club in their right mind would recruit someone who WILL NOT play for them, who WILL NOT even speak to them, who WILL refuse to have anything to even do with them?
Geelong can force Adelaide's hand by ridding itself of its draft picks by way of trading them BEFORE making a formal F/A offer to Danger. At that point Adelaide must match KNOWING that it WILL NOT be compensated for the loss of Patrick Dangerfield. Adelaide forgoes its compensation pick and Patrick Dangerfield nominates himself for the PSD. Paul Connors tells every club of which whom have a PSD pick ahead of Geelong that Patrick WILL NOT under ANY circumstances play for any football clu other than Geelong in 2016, "so just don't go there".
The AFLPA will be up in arms about "restriction of trade". Patrick Dangerfield will be ropeable about having his passage to Geelong blocked by Adelaide who, despite having a compensation pick available to them at the time, elected to not accept the pick knowing that it couldn't extract anything of any notable value above and beyond the comp pick out of Geelong, and have done so just to spite him. That's not a good look.
The AFL under those unprecedented circumstances will either a) offer an additional compensation pick, possibly an end of first round pick to ensure that it most certainly is in Adelaide's best interest to NOT match, or b) behind closed door informs Adelaide in no uncertain terms that by matching and causing such a charade in the process, the outcomes which will ensue will not be favourable from an Adelaide perspective. My guess would be the former.
