NFL Football games only have 11 minutes of actual action?

So there was a study in the Wall Street Journal, that breaks down the average football game. Of the typical game, which lasts about 2 hours and 54 minutes, there are only 11 minutes of actual football. And I always thought baseball was boring.

"So what do the networks do with the other 174 minutes in a typical broadcast? Not surprisingly, commercials take up about an hour. As many as 75 minutes, or about 60% of the total air time, excluding commercials, is spent on shots of players huddling, standing at the line of scrimmage or just generally milling about between snaps. In the four broadcasts The Journal studied, injured players got six more seconds of camera time than celebrating players. While the network announcers showed up on screen for just 30 seconds, shots of the head coaches and referees took up about 7% of the average show." -WSJ
