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 eldest son Jack is celebrating his 18th birthday today and the seven-time Super Bowl champion had an emotional message for him and the rest of the world to mark the occasion. Tom and Jack have been together this week to celebrate the younger Brady's birthday.

Tom Brady's son Jack, 17, towered above his dad in a sweet photo as the pair enjoyed a day out on the golf course, as seen in multiple snaps shared on Instagram.
