Post the whole paragraph as well.
"Voiding of Guarantees. Notwithstanding any other provision of this Section 9, a Club and player may negotiate the circumstances under which the guarantee of any unearned Salary (including, without limitation, Paragraph 5 Salary and/or future year roster bonuses, option bonuses or reporting bonuses) may be voided. This Subsection (g) only applies to the guarantee aspect of the contract provision, and not to the amount that can be earned, and in no way expands the permissible scope of Forfeitable Salary under this Section.
You are making stuff up. Fish posted the language Dallas has used in previous contracts. They are referencing Article 4, Section 9.
The separate negotiated provision that you claim the Cowboys added says, "Player shall be subject to forfeiture of salary to the maximum extent permitted under Article 4, Section 9 of the CBA."
