is how you characterize the guy who makes the video.... again he doesn't represent himself as being some kind of expert... Hes clearly a fan
Hes showing the all-22. Many fans have no idea what it is. When we watch football games and we say man no WRs seem open, or why is the QB holding the ball so long, or what coverage was the defense playing (yes we have people of the board that can tell us that) we can go to the all-22 to see what the QB saw or should have been seeing.
You don't need to be Cosell or Waldman to do that.
