"Rodgers recently
told Peter King of NBC Sports that he’d be interested in acquiring “more freedom” in his next contract, but Brandt doesn’t see a scenario where the Packers would cave on certain “adjustability” proposals, tied to things such as the salary cap and the quarterback market."
That's an interesting juxtoposition of "freedom" and "adjustability" since they are two different things. "Freedom" suggests a player opt-out option. "Adjustability" suggests something along the lines of the rumored percentage of cap basis for compensation. And those terms fit neatly with the rumors about what Rodgers (or at least his agent) is looking for in a novel contract structure.
Players like signing bonuses because it is risk-free money up front. It also creates salary protection in some subsequent years in the form of dead cap. A player's value for any one particular season is not based on his cap number. It's the cap number minus the dead cap that defines value because that's the cap made available for a replacement if the player is released.
I'm sure Rodgers would want the signing bonus cash money up front and the dead cap protection of that whomping signing bonus. Who wouldn't?
From the team and cap perspectives, a signing bonus is an advance on future earnings. It's difficult to envision a contract structure with a large signing bonus in conjunction with a % of cap escalator since the team does not know the future salary amounts against which they are paying that advance. This factor is futher compounded by the expiration of the CBA after 2020. The NFL has offered an extension on the current terms. The union is saying, "no way, Jose", as they have made clear they'll be negotiating for a bigger piece of the pie.
As for the opt out clause, it would amount to early free agency on steroids at the players option, presumably skirting the team's franchise tag option available in actual free agency otherwise an opt out makes no sense. It gets interesting in how much of the signing bonus Rodgers would have to pay back if he exercised an option in the earlier years of the contract.
Add it all up and from the team perspective and "freedeom" and "adjustability" create serious team uncertainties and planning difficulties.
So, "just pay the man", right? Under these kinds of provisions you don't know what you're paying him or how long he'll be "the man".
