line), the quarterback, and the First Level (1L) of the defense. It may alsoinclude mobile personnel (i.e., running backs, tight ends, slotbacks and/orwingbacks) and their Second Level (2L) "mirror" defenders. The core normallyextends in an oval with a radius of 5-7 yards from the football.Numbering: Mobile offensive personnel (that is, potential receivers -- backs andends) are given a number relative to their position. The receiver closest to eachsideline is counted as #1; the next receivers in are #2; while the remainingreceiver, regardless of position, is #3. Reading across the field in eitherdirection, the numbering is always 1, 2 ,3, 2, 1. Stacked receivers are numberedfrom front to back: if the front receiver is #1, the one behind him would be #2,a third in the stack would be #3, and in a quad stack, the fourth receiver at theback would be #2.Offensive receivers are identified with reference to their number and area. Bydefinition, there can be only one receiver in each Area A and C, so receiversstacked behind #1A are automatically #2B, followed by #3B, etc. Similarly, aTE/wingback combination will be numbered (assuming Area A to that side isempty) as #2C and #1B, respectively (see diagram next page). Two importantpoints to note: backfield receivers are identified by number only; andquarterbacks (that is, the most likely passers) are not numbered at all, even indirect-snap (shotgun) formations.7
