Seems a bit crazy to me. Pats depth chart at QB last year was Brady, Garroppolo, Brissett, with Edelman as the emergency QB. The depth chart as of now is Brady. Period. The end. WTF?
That said, a couple things I've heard (FWIW):
1. Pats rumored to have made Garroppollo starter money to stay with the team, but he actually wanted to START. Can't blame him. On that theory, and not wanting to franchise him, it was trade him now or lose him this offseason (with possibility of tag/trade).
2. Pats may want to keep Malcolm Butler, and may need to save the franchise tag for him.
3. Rumors of a second trade coming, with either a pick or Butler plus a pick. Nothing solid on who they are getting, so seems like garbage to me, but hey, BB, so who knows.
4. Hoyer released by SF, so likely Pats take him back as an interim backup.
5. Possible Kraft involvement here. He may have laid down the law on Brady finishing his career with the Pats. Who knows.
