Playing the down and distance (3rd & 17), Greenlaw does not widen out to the flat to follow the RB. This allowed Greenlaw to play the passing lane on the deep Curl. Stafford goes on to work the strongside where Warner takes away the Dig (jd covers this).

Assist to Greenlaw on this INT. Also, this is what happens when chipping Bosa. Perhaps if there was no chip block, the RB goes to the flat sooner and might cause Greenlaw to widen. Any route that is delayed can greatly affect how zone coverages are (not) manipulated.
