Gap lettering (A/B/C/D)

What it is
Gaps are lettered outward from the centre: A between centre and guard, B guard-tackle, C tackle-tight end, D outside the tight end.
Why it matters
The shared coordinate system for all run fits. Every front assigns each gap to a defender; an unaccounted gap is the definition of an unsound front.
Also called
Programs call this gaps, A gap or B gap. The Coach answers to any of them.
