By now, you know the story of how Tom Brady became the New England Patriots' quarterback.

In Week 2 of the 2001-02 NFL campaign, Drew Bledsoe was hit hard by New York Jets linebacker Mo Lewis and was replaced by Brady in the fourth quarter.

The rest is history.

Brady kept his starting job for the remainder of the year and went on to lead the Patriots to the first of six Super Bowl championships, establishing himself as the greatest quarterback to ever play the game.

But Bledsoe never thought Brady would be anything more than a backup:

“When he was on practice squad his rookie year, I actually called my financial advisor about him,” Bledsoe said during a recent interview on ESPN. “I was like, ‘I really like this kid. He’s never gonna be a starter. He’s gonna be Jason Garrett or one of those guys who’s just going to be around forever. You’ll really like the kid.’ And we really liked the kid, we kind of brought him in, he was over at our house for dinner probably once a week. I really liked the kid, and still do. But nobody, outside of maybe Tom himself, would have ever predicted that he would go on to be a starter in the league and be in the conversation as maybe the greatest of all time.”

Bledsoe is surely not the only one.

Brady, who played his collegiate football at the University of Michigan, was originally selected by New England in the sixth round (199th pick overall) of the 2000 NFL Draft, so obviously, he was not a top prospect from the jump.

Here we are, two decades later, and Brady is the GOAT and has led the Patriots to being one of the most elite dynasties of all-time.
