stopping them so long as they are not burned out. So say we could stop them 60% of the time at the beginning, if they are on the field too long, then at the end of the game we would stop them less, say 40% of the time. And if our offense just scores super quickly at first, they have a rested defense and so later on in the game they could stop us more.
I'm sure there is a lot of truth to that.
