JoeyB willing to restructure

[Luvnit2]

If I am calculating this correctly, you are partially correct. They have escalators adding to the guarantee at signing. Here is JJ contract guarantee structure.

After March of 2026, JJ is guaranteed the entire 110 million.

Guarantees
The full guarantees at signing within this contract surmise to $88.743M, which includes the near $37M signing bonus, minimum base salaries this and next season, a $30M option bonus for 2025, and nearly $19M of his 2026 compensation.

Furthermore, another $7M of 2026 salary becomes fully guaranteed next March, and an additional $14.25M of 2027 salary fully guarantees in March of 2026. All of this compensation is guaranteed for injury at the time of signing, and because of the year-early vesting nature, is considered practically guaranteed.

This amounts to a practical guarantee of $110M, and a practical contract value of $125.7M over the next 4 seasons.
