The National Football League, a phenomenally successful piece of the sports and entertainment industry, is largely built around the forward pass.

That's when the quarterback, the star of the show, throws the ball downfield to one of his sprinting receivers who tries to catch the ball and sprint even further down the field.

This can be a very exciting thing to watch.

In recent years, the passing game has gotten even more exciting and more sophisticated, and it has helped drive the league's massive growth.

But if you ask football fans of a certain age who they idolized when they were kids, it probably wasn't a wide receiver or even a quarterback.

It was probably a running back.

The three men we just heard from, we will meet them later.

Two of them are former NFL running backs themselves, and the other has represented many running backs as an agent.

The running back I loved as a kid was Franco Harris of the Pittsburgh Steelers.

To be honest, I was a little obsessed with Franco.

We don't need to get into the details here, but I did once write a book about him called Confessions of a Hero Worshipper.

Like I said, a little bit obsessed.

I liked everything about Franco, the way he carried himself off the field, but especially how he ran.

Some running backs, like Jim Brown, were known for their power, for running people over.

Others, like Gale Sayers, were so fast and graceful that it was hard to get a hand on them.

Franco was somewhere in the middle, strong but elusive, a darter and a dodger.

In football, every play is a miniature drama packed into just a few seconds.

22 athletes moving at once, as complicated as a blueprint, as brutal as war, as delicate as ballet.

A passing play is a bit of a magic trick.

The quarterback and receiver try to trick the downfield defenders into being in the wrong place at the right time.
