Typical stereotype about a certain type of running back who’s just as fast as many other backs. The story says “He isn’t going to be running away from anyone or juking anyone out of their shorts” I remember Zenner running 75 yards for a touchdown against a Top 10 or so ranked Missouri team that had future NFL defensive players. .. Christian McCaffrey was the best running back in big-time college football the last two years. He had hardly been recruited out of high school. He would have never got the chance at Stanford except that his dad was a Stanford star and Pro Bowl receiver for the Broncos, and that he had the grades to get into Stanford. .. Now, he’s expected to be a first-round draft pick, but some of the “experts” are saying he should be a slot receiver in the pros. There’s only one reason people would say that, because he has excellent speed, vision, strength, cutting ability, etc.
There is a similar story in the Moneyball book. There was a guy that some old-school scouts were working out who didn’t fit the stereotype of a speed demon. The scouts refused to believe the 60m times they clocked him in until they ran him against two stereotypical speedsters and the guy smoked them in a three-way 60m.
