In just a few months, Tom Brady will begin the 2018 season as the New England Patriots quarterback. It will be his 18th year in the league - and almost two decades on from the 2000 NFL draft, he's established himself as one of the greatest of all time.

BRADY'S SUCCESS

After entering the league as the 199th overall pick, Brady has gone on to play in 13 Pro Bowls, win three NFL MVP awards and five Super Bowls titles. 

Even at the age of 40, he's far from done - suggesting that he could play on at least another five years. 

Of course, at his age, training throughout the offseason is vital. 

HIS OFFSEASON WORKOUT

The Pats veteran decided to skip his team's voluntary organized team activities (OTAs) - but there's nothing strange about that. 

He is expected to attend New England's pre-season training camp that begins in just two weeks, after already making an appearance at the mandatory minicamp workouts back in June.

Even though Brady has been away from the Foxborough practice fields, that hasn't stopped the QB from putting in some work ahead of pre-season.

BACKYARD TRAINING

In a video first posted on his Instagram story, TB12 can be seen training with his son, working out in his own backyard. 

Now, Brady has never been known for his pure speed on the football field - and he's never been a mobile QB.

But in his son, it appears that Tom has found at least one opponent who he can burn with his wheels. 

TB12'S PACE

Kitted out in a helmet, shoulder pads and one of New England's red training shirts, Brady can be seen faking out his son, before cutting away and using his pace to get around the edge. 

Check out the clip below. 

With that, the veteran QB is finally showcasing the speed we all knew he had. Although, don't expect to see him escaping the pocket too often in 2018.

In all seriousness, there's a reason that Brady's been training away from Foxborough - and it's to do with his personal life. 

A FAMILY MAN 

"This offseason is going to be about my family," he explained in a behind-the-scenes documentary of his life, Tom vs Time. 

"They deserve it. There’s more to think about than just me, and I think that’s what you commit to when you have a family." 

Even with his family commitments, Brady will be returning for at least another year and likely even longer.

But when he does play, don't expect to see him burning NFL defenses the way he did to his son - just expect perfect passes to fly into the hands of his receivers instead.
