ATLANTA — One-by-one the Pro Football Hall of Fame's Class of 2019 was brought together Saturday through a simple knock on the door. 

Hall of Fame President David Baker gets the honor of notifying each class member by going to their hotel rooms and knocking on the door. .

It's an emotional and life-changing moment for "Heroes of the Game." 

Here's a look at some of "The Knock" videos from the 2019 class so far:
