Which is why they'd give him options of clubs. You really think they'll let him walk to Richmond on $700k for their first rounder?
If there is any truth to it this sort of talk would already be happening behind the scenes and they would know what they'll pretty much get before they told him to look around
They. Can't. Trade. Him. To. A. Club. He. Doesn't. Want. To. Go. To.
They tell Dylan they want to trade him this year.
His manager canvases clubs for contracts.
Dylan decides where he'd like to play (based on dollars, years, sentiment, success, whatever).
Dylan nominates a club.
GWS deal with that club for the best deal they can get.
If they can't reach a satisfactory agreement, Dylan stays on and leaves as a free agent (likely to that same club) next year.
You can't try to oust a contracted player and then haggle over which club is prepared to offer a better draft pick in return.
