Judge erases Aaron Hernandez’s murder conviction

Yeah, that might be a different situation. I'm not sure how scheduled (installment) signing bonuses have been treated in the past with respect to players violating their contract. Certainly at first blush, you could assume the signing bonus would be fully owed at signing.

The CBA treats signing bonus's as advanced salary, Atlanta sued Vick for return of his unearned signing bonus. They won their case in court and once he paid they got a cap credit. Another example is when a drafted LB decided to retire after his first year. He had to pay back 3 years of signing bonus.
