As a supporter of a club who hasnt exactly been a pillar of excellence through its life so far, I truly feel for the GC supporters who give their support for that club. A true beacon of incompetence for over a decade now
No the 'dog move' was delisting a Best 22 player to put on your rookie list, all because the club couldn't organize a piss up in a brewery.
This is probably one of the most embarrassing things I've seen happen from a draft perspective. If you're not prepared to lose a player, don't delist them and say you'll rookie them again.
We did it with Abbott a couple of years back, and St Kilda then 'poached' him as ruck back up - but he was just a fringe player. Doing it with Greenwood who's easily in their Top 15 players, was just an insane gamble - that has now blown up in their face in the most spectacular fashion.
This is a very unique situation so I'm not sure what gentleman's agreement you're referring to. Personally, I would say its more scummy to leverage the PSD at the trade table so you can low-ball clubs into giving up their players for cheap which many clubs have done.
