If the NFL and TV networks offered the option to watch games from the camera angles coaches use would you do it? You lose some of the close-up details but you see all 22 players and see why certain plays are successful.
At first glance at the title, I was thinking like a head coaches cam (similar to what the refs used to wear). So you could watch everything from the sideline from the head coaches' viewpoint. Which would be interesting.
But your idea would be interesting, too. I know when you go to a game and you sit up high, you can really see the plays develop moreso when you sit in a lower level.
