Well you need it to run the kicker out, or if you get tackled in bounds, or on a sack. I have wondered about the "value" of a timeout. Is it better to have 1 min and a timeout or 1:15 (or 1:30) and no timeouts? Or, if you have a 2nd and short in the 3rd quarter and the play clock is winding down, is it better to take the delay of game penalty or the timeout? In the 2nd scenario my gut tells me that taking the penalty is the better option simply because the timeout is conventional wisdom which usually flies in the face of the math. here is a big math-heavy article about the topic: http://archive.advancedfootballanalytics.com/2014/01/the-value-of-timeout-first-approximation.html And here is an article that is a little easier for the layperson to digest (think this one deals specifically with the timeout instead of delay of game penalty): https://www.allmysportsteamssuck.com/2015/11/27/dont-waste-a-time-out-to-save-a-delay-of-game-in-the-2nd-half/ "The biggest takeaways for me are that in general, you should always call a timeout when in FG range on 2nd or 3rd down, but on first down the 5 yard deficit is easily overcome. Also, that inside of 10 yards on 2nd or 3rd down you should call a timeout in the 4th quarter for practically the entire length of the field. Certainly not what I expected."
