Walter run the skinny post;
the LCB (Jackson) would turn him in toward the middle and trailed to the outside, guarding the corner route or a come-backer.
AJ ran the crossing route.
The SS would step down to check him.
The RCB (Quin) hesiatated a bit (he needed to be sure that AJ ws not to come back to his side) before he head up top to take over the SS place in the middle.
A little hesitation was all it took.
