Yeah, I don't see many teams employing your strategy. You have 1:50 to move the ball 80 yards, there is no way you're
chewing up 40 seconds of it...just in case. You're trying to move the ball down the field as efficiently as possible. If you fail, punt it away and trust your very good defense to get a final stop. It's easy to make your claim in hindsight, but it's just not what most coaches do at that point.
