I understand what youre saying but game time is game time. There are hours of pre-game and post-game and mid-week shows where Jaworski or Jimmy Johnson or any of the old players show formations that bombed and plays that worked. They run through it like its film day Saturday morning in high school. That is when you get to see the strategy of the teams.
Yeah and the pre-game shows get less than half the ratings of the games, and they still revolve mostly around interview pieces to get to know the players as people and injury reports. The post game shows are hilight packages with very little education. It's only the mid-week shows where they really dig into the X's and O's, and they only get about 1/20 of the ratings of the games. The numbers tell you what the audience is interested in, most folks don't care about how a well run crossing pattern allows you to setup a pick without getting a pass interference call (because you make the defenders pick each other, perfectly legal). And the reason football is so popular is that you never have to learn that to enjoy the game.
