"For decades, NFL TV broadcasts have relied most heavily on one view: the shot from a sideline camera that follows the progress of the ball. Anyone who wants to analyze the game, however, prefers to see the pulled-back camera angle known as the "All 22."
While this shot makes the players look like stick figures, it allows students of the game to see things that are invisible to TV watchers: like what routes the receivers ran, how the defense aligned itself and who made blocks past the line of scrimmage.
By distributing this footage only to NFL teams, and rationing it out carefully to its TV partners and on its web site, the NFL has created a paradox. The most-watched sport in the U.S. is also arguably the least understood. "I don't think you can get a full understanding without watching the entirety of the game," says former head coach Bill Parcells."
