I notice my DBs frequently break off their pass coverage assignments to go after the QB, even when the QB is stationary in the pocket and not showing any signs of running, leaving their assigned WRs to run uncovered across the field. This happens especially on shallow crossing routes when the WR hits the middle of the field, but also other routes as well.
Is there a defensive setting that will make the DBs more likely to stick to their coverages and not try to be freelance pass rushers when the QB is not scrambling?
