If he really has to use bonds man, things are not looking too good for him. At this point he has to consider whether cooperating is the better option or not, right?

Prosecution doesn't need him. Rudy has lied and contradicted himself so often you simply couldn't put him on the stand. His testimony would be impeached within minutes. So his only value would be if he could provide background information that wasn't available through other means. Well they have all of his electronic devices (18 from his apartment alone!), all of his texts and emails, what else can he offer?
