It's unclear why Brady left New England out from his note -- he thanked practically everyone else that he's crossed paths with in his career -- but his former teammate, Antowain Smith (who played with Johnson too), told TMZ Sports he believes the snub was unintentional.

Kraft has not spoken publicly yet about the Brady retirement, though he did release a statement Tuesday saying, "I have the greatest respect for Tom personally and always will."
