Chicago Bears quarterback Caleb Williams went through some growing pains in his first few days working with new coach Ben Johnson's offense. But as the pads have gone on and the reps have increased, Johnson has seen plenty of growth from his second-year signal caller.

Johnson is building Williams into an NFL quarterback from the ground up, literally, as he changes his footwork, rewires his thinking in the pocket and more.

Williams said he and his offensive teammates are trying to get to the point where they're not thinking so much pre-snap, as they work to learn Johnson's offense and its extensive terminology.
