ENGLEWOOD, Colo. -- It is a destination of sorts, even a starting point, a place some are told they have to go, have to get in and stay in. It is the foundation, what Denver Broncos cornerback Chris Harris Jr. calls “everything."
It is routinely still called a book, except it isn’t for most. But how quickly, how efficiently, how thoroughly an NFL player can dig in and master his team’s playbook can determine how their careers begin. And as training camps around the league pound their way to the day when rosters are cut by some 41 percent, the way a player commits his playbook to memory can go a long way toward getting a first chance, let alone a second.
