NOTES: AK= Action Key…this is the first defensive lineman inside #1 (dive key defender). The B-Back must read the way the AK is blocked and determine his course from that point forward.
#1: Dive Key…the first defensive lineman on or outside the play side OT (an inside shade…4i…will be read by the QB)
#2: Pitch Key…the “next” defensive player outside of #1 (we will read stacked LBs)
#3: Primary Run Support Defender…the play side A-back is responsible to block this man; if two deep safeties, the play side safety is #3; if only 1 safety in middle, Corner Back becomes #3).
