First, because Werth is essentially accusing his agent of a breach of contract, and potentially a breach of fiduciary duty as well. Accusing Scott Boras of not doing his job is a bit like accusing Clarence Darrow of malpractice: it gets your attention. Third, the agent must inform the player "Of all facts that come to his knowledge that are or may be material or which might affect his principal's rights or interests or influence the action he takes." In other words, Boras, as an agent, was required to tell Werth whom he'd contacted, what their response was, what the negotiations were, and what any offers were. It's not necessary that Boras supply Werth with verbatim transcripts of every conversation, but he does have to tell Werth that conversations occurred and what was discussed. From Janes' reporting, we know Boras sent Werth's name to all 30 teams, and he made phone calls during which he discussed Werth with at least some team executives. It's not even whether telling Werth to wait in November was bad advice; bad advice, by itself, does not constitute a breach of fiduciary duty make, and it's at least reasonably defensible for Boras to recommend Werth wait out a slow-moving free-agent market. If teams were waiting to hear from Werth about offers that had been extended, and Boras never told Werth about those offers, that is a prima facie breach of fiduciary duty.
