Tom Brady carved out a stellar career in the NFL thanks to his unflappable in-game persona and once-in-a-lifetime arm skills. The seven-time Super Bowl champion was anything if not stoic during his 23-year NFL career, but Tom Brady 2.0 is an entirely different person.

Tom Brady's son Jack turned 18-years-old and the former QB markd his special day with an emotional post filled with words and pictures.
