The problem is, clubs have very little to trade.
Anyone who has been a regular in the 22 is usually parcelled up, with the occasional exception that slips through like Ryan O'Keeffe. At the end of the day, he will probably sign up with Sydney anyway.
That leaves fringe players and most clubs are trying to trade them for early picks, which are also parcelled up. This is the wrong philosophy because they are all trying to screw each other over, when they should be co-operating to get a win-win.
None of the clubs treat the period the way it was intended, which is to provide an opportunity to swap excess players for something that they need. Everyone wants more picks but they should be looking at player-player trades, and not just offering up the last four players on their list, who they will delist next week anyway . Clubs should be looking to give up a regular best-22 player to get someone they really need, like a ruckman or a CHB or whatever. It will fix the problem and create space for a younger player to come up and replace the player moved on.
Of course, the salary cap doesn't help.
