I found this little post in the Providence Journal, I guess that over the 3 to 4 hours of a game, there is plenty of time to get a refill for that glass of Coca Cola, LOL

The Wall Street Journal points out that in football, unlike in most sports, the clock runs for long stretches while nothing is happening.

So The Journal broke down some telecasts to find out how much football is actually played during an NFL game:

"The average amount of time the ball is in play on the field during an NFL game is about 11 minutes. In other words, if you tally up everything that happens between the time the ball is snapped and the play is whistled dead by the officials, there's barely enough time to prepare a hard-boiled egg. In fact, the average telecast devotes 56% more time to showing replays.''

"The ratio of inaction to action is approximately 10 to 1.''

Something to think about as you're sitting on the couch next Sunday.
