The buzz in league circles is that Brown wasn’t aware of the amount of cash hinging on his participation in offseason workouts.  On one hand, he signed the contract — and arguably he should have read it.  On the other hand, his agent (who has a clear incentive to see Brown maximize his compensation) may have failed to explain it to Brown. 
Either way, Brown’s agent probably should read his malpractice insurance policy.
