His cap hit is 49 in 2023 and 52 in 2024. So by the time you move more money into his signing bonus you're just increasing his 2024 hit.
again it doesn't work that way.
They will lower the cap hit every year either by "scheduled restructure" or extension or adding void years.
Void years costs Dak nothing so a free mechanism.
There is a small gamble here of course as if Dak was seriously injured your stuck.
but outside that you are simply floating that money along.
When he gets extended which is likely to be before the first league day of 2024 they'll remove the void designations from the early years, hand him a massive signing bonus and a minimum salary.
It'll get that yearly down to around 30M. And they'll continue on that path.
There are like 8 QBs making more than Dak go look at how their cap hits are stretched out.
Rodgers is making 28M, 31M, then 40M, 59M, and 53M.
After 2 years they'll move that money if he is still around for year 3.
