The Bengals are in a 3-2-6 Dime personnel.
The DE backs off the LOS pre-snap to a LB depth & alignment.
Mike & End crossfire in the A gaps. Mike is 1st - End is 2nd
DT's - Working B gap to Contain
Will - Man on the RB
SS - Man on #3 strong
Dime - Man on #1 weak
Corner & Nickel man on #1 & #2 strong
FS and Corner - Deep 1/2
The coverage looks like a 1 high coverage pre-snap but becomes a 2 deep coverage post-snap. A 4 man pass rush that looks and feels like a 6 man pressure helps speed up the read and throw for the QB. Tight aggressive man under 2 deep coverage makes the windows to throw into very small. Coverage disguise + perceived pressure + tight coverage = effective 3rd & 9 call.
