Tom Brady Candice Ward-USA TODAY Sports

Future NFL Hall of Fame quarterback Tom Brady underwent one of the most public divorces in league history in his final season with the Tampa Bay Buccaneers.

Some fans are speculating Brady’s recent Instagram post might be him dealing with the pain of not regularly seeing his children.

On Tuesday, the former New England Patriots star posted a long quote from Muhammad Ali about South Africa against apartheid.

Brady chose a cryptic title for the post: “Be proud of the man in the glass.”

Brady wrote on Instagram in the caption, “The personality of a person. The ways of a person. His thoughts. His deeds. His actions. Are all based around his heart. For what is a man? A man is his heart,” the Ali quote reads.

“A lying cheating heart means a lying cheating man. A loving merciful heart means a loving merciful man. A living heart means living man. A dead heart means a dead man. Regardless to a man’s title. Regardless to a man’s rank, wealth or position, if the heart is not great then he cannot be great. But if the heart is great that man remains great under all circumstances, rich or poor, large or small, for it is the heart that makes one large or small.”

Brady did not immediately explain the post with Christmas coming next week.
