If Flynn jumps to another team before the Dolphins either sign Manning or abandon the hope of signing him, it should speak loudly about the perceived relationship between the pair. Put yourself in Flynn's shoes for a moment. If you believe that Philbin thinks highly of you (they've got to have a good understanding of that by now), wouldn't you wait to sign a contract in order to either drive up your price or, even more critically, sign with the team where your familiarity with the offense will best suit you?
