If the TV doesn't capture it then it leads to nothing important. Besides, when I was a match goer I spent the vast majority of my time watching the ball (and cursing...)You definitely get anything like the same sense of whats going on off the ball on TV. Obviously if there's a goal or whatever they'll analyse it after the event so you can see, but the camera by definition will be focusing on the ball so for 99% of the play you have no idea what a player is doing out of shot.
