By being salary cap free, the player has no need to show loyalty to the club and will expect the club to pay them the same or near enough to, as it is 'cap free'. The poorer clubs may get an exemption from the cap but they still need to find the money from somewhere.
My issue is that the clubs AND the players need to reward the loyalty, not just expect the clubs to foot the bill.
But you can't begrudge a bloke his 'last big payday' can you?
Most of them will never again earn the kind of cash they can earn during their playing years - sure, its fine for a Hindmarsh or a Lockyer to be loyal and take less if they have something teed up in retirement.
I think your interpretation of loyalty is 'get paid peanuts'. That's not at all what loyalty is? Loyalty is wanting to stay with the same club, and perhaps even taking less to do so. HOWEVER, to do that under the current system can become very difficult when it is the last payday....
Example:
A player has been with a club since he was 18, he is now 30, and wanting to sign a last 3 year deal. His best days are past, was once an fringe Origin player, certainly still has a lot left to offer a club, but isn't the $450k player he once was. More like a $100k guy now - good vet to have around, not someone who is in the conversation for man of the match much anymore.
Last seasons wooden spooners need a 'name', they are willing to throw $250k at this guy to get a profile player, and to attract other name players to the club.
The guy has had a long career, wants to end it at his original club, but has 2 kids and there is $750k on the table for a 3 year stint, or $300k.
Taking a big payday doesn't mean he isn't still a fan of his original club - he may well end up being a club legend and getting involved with them in some way. Still LOYAL to them, but give the guy a break, he needs to earn some money for his family while his body holds out.
He goes to the club in tears, 'I wanna stay' - the fans are irate 'he is our just above average first grader, and we love him, pay him!' - what do they do??
The proposal put forward is good - doesn't force the poor bloke to screw himself NOR does it force the club to screw him over. What is more, it enables them to build loyalty and culture and a desire to stay at a club long term. It's worth it!
