All contracts are supposed to have a two week period between when they are received by NRL club and announced as official by club (the club not retaining the club I believe can waive this period, although most times neither club probably worries about that)
Looks like we are at bang on two weeks since it was announced, but I imagine every single contract they were making progress with suddenly went back to the drawing board with money hungry managers (not that the players wouldn't also like more money).
But anything confirmed over the next week after the changes would still be a week away from being announced.
Access to more money may have also brought other players into their sights they thought they couldn't get, which may slow down some of the negotiations they had ongoing, with lesser players.
Humphreys I believe was widely rumoured to be done deal but hasn't been formally announced yet months later...
Think they have 20 players signed to top 30 currently, but would be having to run Apa Twidle or Nick Meaney at 6
(adding in: just saw Dylan Walker tried to get a deal with Perth but 'they weren't interested' - so they are being discerning still, as I'd have thought he'd be a fine signing. Maybe would have been if he had lowered asking price, doesn't touch on if that was a factor)
