I really welcome this notion, I support the player, not the club.
That being said, it's hardly an issue of paying Hayne too much. If anything, he's probably the best value per $ in the club atm.
What's more worrisome is that a big chunk of Parra's cap seems to be devoted to:
1. Corey Norman -> was a desparate signing for the sake of having a 'potentially' first grade level 5/8. Gamble failed.
2. Chris Sandow -> The biggest gambler (not referring to off-field issues) on the playing field. Will look absolutely untouchable when it pays off, but the entire team suffers when it doesn't.
3. Will Hopoate -> No doubt on the class and talent on this guy, but this entire season has shown that he still has a LOT of work to do in order to gain what he lost the past 2 years -> Again, another risky signing that didn't pay off this year.
I won't quote exact, or even estimated, amounts i'm pretty sure most people are aware that these 3 also take a big part of your clubs cap under the assumption they'd at least perform to some expectation (even though it seemed really unlikely at the time of signing).
At least on the big money Hayne is on you get a player that AT WORST is still fairly solid throughout the year.
