One of the perceived limitations of so-called "spread" offenses is that they tend to struggle finishing drives in the red zone. The conventional wisdom is that as the field shrinks, the amount of space available in which the offense can stress the defense vertically is limited, which gives the spread offense's athletes less room to operate. Much of this consternation with spread teams is Gilmorian, in the sense that just because wisdom is conventional, that doesn't make it correct. However, space is an issue in the red zone, and the Air Raid is certainly all about creating space in the defensive backfield.
