The salary cap would need to go up a hell of a lot more than $10m per season for even the best players in the game to demand more than what Hunt is on.
Only the top few players in the game are worth 10%+ of the salary cap.
You cant pay a solid player 10% of the salary cap while guys who are just as good or possibly even better earn half that. Thats the sort of thing that makes them look elsewhere.
Percentages are the key here to assessing a players value.
People are getting too caught up with the 1M per season price tag when in reality if a player is worth 750k under a 7.5M cap then he's worth 1M under a 10M salary cap.
It's all relative and equates to exactly the same value.
Imo Ben Hunt is definitely worth 10% of a club's cap. He doesn't have a great short kicking game but there are plenty of things he does do well - an excellent long kicking game, high involvement as he's always a threat and around the ball, and a great running game.
If the Dragons make some smart decisions - admittedly not likely with Doust - and surround Hunt with a couple of spine players that do have a good short kicking game then he'll thrive doing what he does best.
But if they don't surround Hunt with the right players to compliment him then he probably won't fulfill his potential at the club.
