While football players have gotten bigger, stronger, and faster in general over the last few decades, the variety of body shapes in the league is actually higher than it has ever been.

Journalist Noah Veltman made a great visualisation of how NFL body sizes have changed over time. Notice how the spread of types has gotten larger and the density of specified height-and-weight combinations has gotten lower:
