The "All-22" footage that the NFL won't let you see.

The WSJ explains about those camera shots "from on high to show the entire field and what all 22 players did on every play" which are most useful for understanding the plays and never shown on TV.

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....

Without the expanded frame, fans often have no idea why many plays turn out the way they do, or if the TV analysts are giving them correct information. On a recent Sunday, San Francisco 49ers quarterback Alex Smith threw a deep pass to tight end Delanie Walker for a 26-yard touchdown. Daryl Johnston, the Fox color man working the game, said Smith's throw was "placed perfectly" and that Tampa Bay Buccaneers safety Corey Lynch was "a little bit late getting there."

Greg Cosell, producer of the ESPN program "NFL Matchup," who is one of the few people with access to All-22 footage, said the 49ers had purposely overloaded the right side of the field so each receiver would only be covered by one defender. Lynch, the safety, wasn't late getting there, Cosell says. He was doing his job and covering somebody else. Johnston could not be reached for comment.
